This links to a simple tape eraser.  It's output is very high, meaning
short application times might be used for very quick application
against germs in lymph nodes, etc.  The problem I see with it is heat. 
It only allows a 1 minute application then it must be cooled down!

However, that may be enough for covering half a dozen lymph nodes with
a 5 or 10 second burst, or even the entire liver with high energy germ-
inactivation without any skin contact.

This might be interesting to investigate, but I wonder about the safety
of using 60 cycles heavy magnetic fields like this on the body.  If it
could be set to a lower frequency, like 4 hertz or below, it might be
less of a question.  I know Beck said something about "keep it below 4
hertz" on one of his videos, but the question was indistinct.  Those
videos were criminally bad quality.
