Suppose a 10k Gauss 3in diameter sharp magnetic field is made & collapses completely thru a standing human human body somewere made by an external electromagnet.. The electromagnet is held horizontally and not vertically against body. Is this hazardous? Can it become hazardous after some duration with repetitive pulses? How many orders of magnitude greater would the Gauss need to be increased to become a lethal shock hazard from 1 pulse?
