KMoffett is right: Health and safety of the forum members is never "off track".

 

Here is a schematic of what I'm building not pretty but it will give you an idea. I still have a problem with the relay as it welds the points together. I need to find another way maybe a solid state relay. I have played around electricity all my life and have a good respect for it but when it comes to certain things I seek out help.
When it did work it help my mother in laws neck pain and fixed my aunts shoulder

 

Just curious: That must be a "pancake" coil? Wider in diameter than it is tall? How many turns do you have?

 

I used a old spool from a VHS tape and wound about 120 turns the recommend 120 to 130 turns but I could not get 130 turns on that spool

 

Just an up date on the machine after using it for two years. I have seen people become pain free in minuets. Also one women who had cancer and had a lot of pain got the first nights sleep in weeks with a few minuets of pulsing. Although I done think it is a cure but it does make life easier. Here is a video that has an explanation of what is going on in the body.

 

there are things like this on the internet, search for "can crusher" using a very high magnetic field to crush cans and quarters. lots of design info.

 

A follow up after using the PEMF unit for now than 2 years I have concluded that with a 50 Watt transformer I could pulse every 10 seconds and with a 1 amp transformer I could pulse and 5 seconds.
I have used it on arthritis pain and got relief in less than a minuet also other pains. There was a problem here in the Dominican Republic with a problem called Chikungunya that causes a lot of pain in joints it work almost instantly and it did not return. It also help a person with pain related to cancer the person was unable to sleep but with a treatment was able to sleep through the night. I don't think it is a cure but it helps with pain control as far as I have seen.
Thank everyone for their help and concerns

 

This is kinda interesting, maybe build one and try it on my 13 year old dog, she is having a hard time with her joints. With a 250 volt Mosfet and higher voltage caps my experimental LED flash could easily be adapted using a switch to trigger the 555 and replacing the LED with a coil.

Come to think of it, may get away with the 80 volts I am now using, just need to figure out what the coil needs to be to do what 120 turns on a VHS tape spool does.

 

I had a cat with joint pain and it was dramatically improved after feeding it glucosamine. (I can't recall if their was also chondroitin in the product. Glucosamine is much cheaper.) Just sayin'.
