It means to make something not magnetic anymore
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.
heating the magnet past the Curie point
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!!!
Magnets are "demagnetized" by extreme heat. If you boil a magnet in water, the heat will demagnetize the magnet.
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 out
"It is best to demagnetize metal objects before using them around magnetic tape drives." "Heat tends to demagnetize ferrous minerals."
no you can't
By keeping them in magnet keepers

lucky rabbit's foot
Obviously no.
No. Steel is mostly iron.
you rub a piece of sand paper on it
demagnetize
We demagnetize our instruments with a commercially purchased demagnetizers.
What do I need too do
Let it sit on a magnet overnite
