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
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!!
Because the domains get muddled up and eventually return to a random order.
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.
what is the diffrence between a magnetised nail and a unmagnetised nail
