With most of this technology we are pushing the linear magnetics and  emf's way up.

 

The magnetics feilds created are harmful and can effect phase lock loop circuits. 

 

We need not slow down nor cancel or reduce any experiments or designs but simply we must be accutely aware of what exactly we have on our bench.                                                                          

 

This page is to raise the common knowledge of how to measure and see into the magnetics.
