Hitting a magnet may affect its magnetic domains and thus may remove its internal magnetism, thus the magantism may be reduced or even removed by hitting it.
Yes. Different alloys make different strengths of magnets.
Yes, a magnet looses its power if hammered .It also looses its power if heated or subjected to AC.
it doesnt really affect its magnetism it just become more attraactive or less attractive.
yes
the magnet gets weaker
the magnet gets weaker
it attracts
Usually nothing.
When some pieces of plastics are brought near the magnet, they will get attracted.
the magnet gets weaker
If you drop a magnet it will hit the object under it
Move towards the U magnet so that the poles attach.
the nail goes to the magnet
Nothing happens, it does not attract.
a magnet is a solid so you don't freeze it
it will loose its magnesium
Assuming it has a robust rigid construction so it doesn't break easily : Nothing. If it is hit hard or even dropped repeatedly however, it will put the atoms out of position and lose the magnetism
the metal object becomes a temporary magnet
the magnet gets weaker
Nothing.
stick it
