Re: [Vo]:Watch a Powerful Electromagnet Shrink a Quarter to Half Its Size

I don't think so.  Electric fencers are relatively high voltage at 10Hz
AC.  They are limited to very low current so you don't kill what touches
it.  The 10Hz AC is very painful.

[Vo]:Watch a Powerful Electromagnet Shrink a Quarter to Half Its Size

I thought this was very interesting.  I wonder what would happen to a
loaded electrolytic cathode or TiH2.

"Shrinking a quarter down to half its size sounds like a magic trick, but
there’s nothing magic about this experiment highlighted by Physics Girl
 Dianna Cowern.
In the video above spotted by Nerdist
,
she explains the remarkable physics at play when a coin is at the center of
a powerful electromagnet.

The rig featured in the demonstration is powered by a 160-pound capacitor
capable of charging up to 8000 volts. For a little perspective, that’s
similar to the amount of power delivered by some electric fences
. "
