You can bash it on a table to bash the magnetic domains around
and they mix around so they can't stick to another magnet. Test it
Dropping it on a hard surface
Generally speaking, striking a magnetized object sharply tends to demagnetize it.
ironically, one way is to hammer it, as in smashing it can cause it to lose its magnetism.
Heating and hammering will demagnetize .
We demagnetize our instruments with a commercially purchased demagnetizers.
"It is best to demagnetize metal objects before using them around magnetic tape drives." "Heat tends to demagnetize ferrous minerals."
to demagnetize a magnetized steel bar, just hammer or heat it .. that works !
Bring it to me. I will do my "special technique" to demagnetize it. You know, sell it and not give you any of the money. Gold isn't magnetic, so if you got some that IS it's got iron in it.
a way to demagnitize somthing is to not get it magnetized :) simple as that :)
It means to make something not magnetic anymore
you rub a piece of sand paper on it
No. Steel is mostly iron.
A sharp blow with a hammer should do the trick. The atoms in the tweezers are all alligned north/south, hitting them should dealign the atoms and therefore demagnetize the tweezers. Be carefull not to damage the tweezers!!!
because it can magnetize and demagnetize easily
heating the magnet past the Curie point
