"Our Neodymium-Iron-Boron magnets are approximately 75 iron, and have a surface protector to prevent corrosion"
The iron in the magnets construction suggests saturation problems.
Do they provide a B-H curve? This would help you to see whether there is a margin between the static flux and the saturation level.
In respect to your suggestion, Another way to do it would be to use a ferrite core and a DC current superimposed on the AC current to provide the "DC field" with the AC imposed on it, ie. don't use the magnet
Do I take it that a ferrite core is preferable to the neo-magnet then, or could I just use a strong ferrite magnet within the inductor? Maybe it's back to the drawing board, Len. I'm not an expert on magnetics. The point of ferrite is that it can operate at higher frequencies than an iron core.
The same question as above occurs to me about ferrite, ie. see if you can find a B-H curve for a ferrite magnet.
As explained to Hero999 in my previous post, my main aim was to superimpose and add the circuits varying pulsed output upon the magnets very impressive static gauss of 10000, thus giving a larger overall field strength. This would hopefully give me a larger depth of magnetic penetration into biological materials. I'm certainly not an expert in this area. But I'm dubious about your claim that the static component will give you a deeper penetration.
I wonder whether you simply need a strong alternating field or, as you claim, a static one with an AC component. Note that you may not be able to make the latter alternate. To make it alternate, the AC component has to be stronger than the static field so that on "negative half cycles" the magnetic field reverses (which is what I mean by alternating). Otherwise, is it just a static field with an AC variation - if you see what I'm trying the say.
Kind regards as usual,
