Ok BvU, well it seems I have wasted your time. It shows how easily I can be baffled both by accepting published science papers, and by my limited understanding. Result: a couple of coils and a frequency generator ain't going to fix my arrythmia! Still, many thanks for your advice. Regards John

Thanks for your interesting responses, and for taking the time to think about this. Here is a link to the paper i referred to http://www.thatchmasters.ie/Astro/Document.pdf As it was published in the medical literature I thought it was legit. Do you think its all bullology? As a sufferer of AFib...

@BvU Yes, understood, a nice idea! It seems that low level emfs do actually have quite an effect, as the paper i referred to has found. Here is some background: https://www.drpawluk.com/health/electromagnetic-fields-and-the-heart/ Maybe i am approaching this from the wrong direction. Is there...

Thanks BvU, I am blindly following the original paper as they had success suppressing fibrillation in dog's hearts by targeting that particular molecule. Are you suggesting to scan through the frequencies when you say pirouette?

The problem statement: I want to produce an LL-EMF of a specific amplitude and frequency in a pair of Helmholtz coils of pre determined radius. The frequency and amplitude are derived from the following equations from this publication...

Thanks jedishrfu, Where should i post a question about the design of a Helmholtz coil? I have solved the equations but get an unlikely answer. Could be maths mistakes or misunderstanding the necessary steps. Or just being an idiot. Electrical Engineering i thought?

Hello Everyone, I am over 60 (yes, there still is life there), and have a lifelong interest in Physics. As one of my teachers used to say, "Physics is Fun!" These days i am playing around with raspberry pi computers, using the camera module as a video doorbell, and in the process learning bits...
