Has anyone noticed,or has a reason,why a #3(?) multi stranded copper wire bends, when about 300 amps of D.C. current is shorted through it?Ive worked on cars for years,
and when I get a starter that is shorted out,Ive noticed,when under the hood,
the positive cable,if long enough,will try to bend.It moves.Ive never tried to bend the wire to see if its turning solid.Is this the magnetic field of the wire reacting to Earths magnetic field?Or is it the electron current trying to straighten the wire?Ive tried to measure,using a micro-gram scale,if the weight of the wire was actually decreasing (opposing the Earths magnetic field).Using a very small wire and battery (balance is very picky,all that I have)it appeared that it actually got lighter.Other tests showed it got heavier,I am talking micro-grams of difference and burning wire.Has anyone else observed this?I know this is anologous to a flashlight bulb,(D.C. not A.C.)but those filaments are attached.
