Haven't had a lot of google time, but so far this is what I suspect:
The source is not really a square wave that goes from + to - but either from + to 0 or - to 0.
More googling next week. Early setup for another gig today.

I think it does matter. It's not just a coil. It's a coil around a core.The North /South poles of the magnet will reverse.

Where did you find out that there is a core involved, John?
Even with an iron or ferrite core, I don't think polarity will be an issue, simply because if you tried to hit the coil with a DC pulse, the collapsing magnetic field of the core would then generate a back EMF in the coil, which would also generate a magnetic field of the opposite polarity for that part of the time, then the whole thing repeats again with each cycle.

OK, in my research, I found a PEMF unit that does what I want my home-built unit to do, for less than the price of a decent gaussmeter (which I would need to measure my results).
So I'm probably going to get that unit instead of building my own.
PEMF therapy is supposed to relive arthritis, reduce tinnitus, reduce 'senior moments', improve eyesight, and number of other things that might be of interest to musicians.
Is anyone interested in keeping this thread alive and reporting results?
If yes, say so, if not I'll let it die.

While I do wish you well with your experiments, I must state that whenever a single item, be it an herbal "cure" or a machine, touts long lists like the above listing all sorts of claims as to the ailments it supposedly has cured, to date every one of 'em has been the proverbial snake oil.
A hundred years ago or so, the big thing was Diathermy.
Today, the remaining pieces of Diathermy apparatus foisted off onto the public are the things of collectors and museums where people marvel over the gullibility of their grandparents.
Have Fun, Notes, but by all means please be skeptical here.

Hmm, I thought I already answered this, but I must not have hit the "Send" button.
After extensive googling, I found that it does need to be a pulse, preferably zero to north polarity.
I also found a commercial unit, that does what I want and costs less than a decent gaussmeter that I would need to test my build. So I'll probably spring for the commercial product.
Now PEMF therapy is supposed to do a few things that might be of interest to musicians (1) relieve arthritis (2) reduce tinnitus (3) increase brain power - of course these things are not FDA approved, and not guaranteed to do any of the above. Also, one uses them at their own risk. But they are approved in Europe and other countries for these symptoms, and also approved by the FDA for bone healing after a fracture.
If anyone is interested in reports and/or progress let me know.
If not, I'll just let this thread die.

My feelings exactly. Especially when something claims to cure so many different diseases. If we couldn't have tried it so inexpensively, I would have shrugged it off as snake oil and not even drove to the 'clinic'. But mother-in-law wanted to try it.
When we took my mother-in-law down it was an act of desperation. Brother-in-law the surgeon said it wouldn't hurt and was probably worth a try as the PEMF machines are approved in Europe, Australia and many other countries plus here in the USA they use them for bone healing and in pain clinics ... and in addition they are used for veterinary medicine, especially to relieve arthritis in race horses.
But her current problems weren't Parkinson's related. She had a pinched spinal cord and needed surgery to relieve the pressure. So any PD improvements were masked by the pinched nerves.
So Leilani and I figured since it won't hurt, and since it was less boring than waiting in the waiting room, we could lay down on the lounge chair and get zapped ourselves.
So after a few weeks, I'm looking at my droid phone keyboard, and I can see the difference between the comma and the period. My glasses are old and I'm overdue for a new pair. Even when new, I couldn't read tiny type as the compromise between near and far objects put close focus at about relaxed arms length (book reading length). By the end of the month I could read tiny print anywhere, on the back of those pink sugar substitute packets in a restaurant, and everywhere else. I find myself looking for small print to read, and in decent light I can read anything (with my present glasses). Haven't been able to do that in 20 or more years.
I have an injured small finger on the left hand. Probably from the days when I played basketball. It's been bothering me a lot when playing guitar, playing G#s on the sax, and using the left Shift key on the computer. Pain was all gone. This was like magic because that joint has been bothering me for decades.
I have bursitis in my hip and have had that since high school. Runs in my dad's family. By eating an alkaline balanced diet I got rid of 90% of it. Since the PEMF I can jump up and down and it doesn't bother it a bit (I still eat the alkaline diet).
Leilani had eyesight improvement and increased joint comfort as well.
And as the months passed after the 'treatment' my eyesight started to revert and my finger got some slight discomfort back - but not the strong pain when playing the guitar like it did.
So I'm starting to think it isn't snake oil at all. Not that I believe all the claims about it, they just seem too good to be true. But for joint pain and eyesight it seems to work on us.
So I've done a lot of googling to find that NASA uses PEMF whenever humans go into space, including the space station. It seems the earth itself has a pulsed electromagnetic field of about 9.6Hz and the animals that evolved with it can't live without the magnetic field. The magnetic field gets weaker and weaker with distance, so the people who spend days or months in space need the pulsed field or their health will degenerate. NASA uses a square wave, north polarity, at 9.6Hz.
Also studies show that the earth's magnetic field has been steadily getting weaker, which is why some scientists are predicting another reversing of the poles. But this get beyond fact and into guesswork.
The medical profession in Europe has had remarkable results with the majority of Parkinson's Disease patients and a number of other diseases.
Pain clinics pay up to $60,000 to buy a clinical machine that does the entire body at once (like the ones we laid on at Ernie's "clinic").
According to what I've googled: It seems to work with calcium, which I found out is paramagnetic (magnets affect it but it doesn't stay magnetized like iron). According to the theory, calcium is constantly being replaced in the bones (this part is a fact) and the old calcium lodges itself in the joints and the nerves. The pulsed magnetic field shakes the loose calcium and if you drink enough liquids, it flushes out with your urine.
So I figure (1) it can't hurt and (2) it certainly helps my finger, hip and eyesight, and (3) if there is a chance it will help mother-in-law's PD, it's worth a try anyway.
So while I remain skeptical about the PD, if it helps her arthritis like it helped my finger and hip, that's good enough. If it helps the PD, it's even better.
So I've plunked down some bucks and I'll let everyone know what we are experiencing. Positive, negative or nothing at all.
So while it won't make you handsome Mac  it might help a few of us with arthritis problems.
I won't know if I don't try it. I'll keep you all posted as long as anyone is interested. If not I'll just let the thread die.

For Mac and the other skeptics (myself included) there is a lot of very positive information about Pulsed Electromagnetic Fields on the U.S. National Library of Medicine - National Institute of Health web site. 1200 peer-reviewed published studies are listed here. http://www.ncbi.nlm.nih.gov/pubmed?term=pulsed%20electrmagnetic%20fieldThe more I learn about this, the more I actually like it. Of course I'm hopeful, especially for my mother-in-law so that is bound to slant my view, but on the other hand, as a natural skeptic I am doing my best to keep my hopes and wishes out of the investigation.

Here are the conclusions of other peer-reviewed scientific studies about PEMFT along with the name of the study if you want to read the abstract. http://pulse4life.com/docs/Scientific_Studies_On_PEMF.pdfAnd as for the effects on me: My arthritis, and bursitis is gone - completely. PLUS: My brain is sharper, my energy level is up, and my vision is much better. I'm farsighted, which means nothing is in focus, but far things are less out of focus than near things. The compromise in my glasses was near focus is sharp at comfortable distance and newspaper sized typeface. Now I can read the tiniest print and can focus on things about a foot away from my eyes (with my glasses). Leilani has had similar results. Her arthritis is lessened but not gone yet, her vision better (she's nearsighted), her mind is sharper, but her energy level hasn't increased (but I don't think it needs it). The $600 machine will pay for itself in the supplements I'm no longer taking. They offer a 90 return policy, but they aren't getting it back. I've ordered another for my mother-in-law to see if it will help with her Parkinson's and never damage. Both conditions have peer-reviewed mostly positive papers published. Of course, this isn't a scientific double-blind test, but merely my personal experience with the device. But I'm sold. Notes

Hang in there. I'm in the process of setting up a web site to talk about PEMFT. Should be up today, I'll post here when it's done.
That will keep long OT posts off the music forum.

OK, I've started a website http://www.pemft.info that explains my journey into PEMFT (Pulsed Electromagnetic Field Therapy) from day one. Please read the home page. I gave the condensed version here when I was trying to build my more powerful PEMFT device, this page gives the whole story. In this site:
- I plan to include all the science based information I found (and not the hype) from my hundreds of searches on the web. There is no place with all the information in one place - I'm going to try to correct that
- It will be advertiser supported so that it can remain free
- I'll include pros and cons
- I plan to include comparisons of the various commercial devices with their waveforms, field strength, etc. - this information is difficult to find
- I'll also include verified testimonials for different devices
- Note: since you asked -- the top ad on the "where to buy" page is the link to the $600 device I'm currently using. If you plan to buy, please use that link - I'm hoping the ads will support the site.
So why the website? First of all, I have put thousands of hours googling this and it was frustrating. I like writing HTML code so it was fun to create the website. I found a good deal on a web host that the ads should pay for. I don't expect to get rich on the ads, but as long as the ads support the page I'll keep it up. Most importantly, while I started out skeptical, I'm very enthusiastic about this technology. Because of the difficulty to find good information, I paid way too much for a much weaker machine before I found the better one. And I didn't want to be responsible for a health-care decision for anybody else but me, so I found peer-reviewed, scientific articles about PEMFT and included them on the site. That way if you want to do this yourself, you can make in informed decision. Now I've recently started putting the magnet under a 4" "memory foam" topper and sleeping with it. Not in the "sleep mode" (I have no trouble sleeping) but in the more powerful "recover mode" (I would suggest trying the sleep mode first to get used to it, but I've been doing this for a few months now). The arthritis in my little finger is completely gone, Leilani's arthritis is lessened considerably. I typed all day yesterday creating the website and neither the injured little finger nor the former "trigger finger" on my mouse hand have any sensation at all. My mind is more alert and I have more physical energy. Leilani's mind is more alert but she always runs at maximum physical energy. It's magic. So I'll continue to give reports on my health experience, but for any more questions, please go to the http://www.pemft.info site.

Not just Magic, Notes ole bean, but since yer gettin' into technology, the terminology we like to use around here is to tell 'em its, "FM". The M stands for Magic, be creative as to what that F stands for. As in, "How does that work?" "Its FM." --Mac
