Yes its very much related. Pulsing magnets are shown to create micro-currents in the body...micro-current machines now being shown to do all this amazing miraculous stuff.
So basically the earths core being a pulsing magnet does what these machines do.
Since I made that post a few days ago I came across this device...it mimics the earths core in a pulsating magnet that you put under your mattress and sleep on.
It's like mega-doses of earthing. I've seen videos of people with Parkinson stop hand shakes after using it for only a few hours, the inventor of the machines dog has been sleeping on it for 7 years, is 16 years old but looks like it hasn't aged 1 day.
I prob wouldn't believe the videos but some of the worlds leading magnetic therapy Dr's including the worlds leading earthing proponent are advisers for the product.
