banging the magnet makes the 'mini-magnets' inside the big magnet go back to the way they were before magnetism. xx
By banging a nail it causes all the tiny domains to face different directions so you end up with a non-magnetised nail.
what is on the nails is ltlle partials and the banging nocks the particle off
Rub the nail vigorously against a magnet. The nail will now display magnetism.
When you bang the nail the domains in the material you are banging jumble up to face different ways so the material is no longer a magnet!!
the magnet is in matter is called magnetism
Because the domains get muddled up and eventually return to a random order.
It makes all the domains of the magnet jumble up ( they all turn separate ways ) So the nail is no longer acting as a magnet
A nail made of steel.
if you have a nail and a coil rapp the coil on the nail and put the nail on a magnet
No.
Electric current in a coil can induce magnetism in an iron nail,place near the coil.when the electric current is cut off the magnetism in the iron nail disappears.the magnetism in the nail exist so long as there is electric current in the coil.this is an electromagnet.
The steel nail will rust.
