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.
the magnet gets weaker
it attracts
When some pieces of plastics are brought near the magnet, they will get attracted.
Nothing happens, except that now you have two magnets. The poles of a magnet are not actually localized at the two ends of the magnet but are inherent to the magnetic properties of the magnet. As the magnetic properties are not altered by a modification of the magnet such as cutting it in half, there will be no effect on the poles of the magnet.
You can use a magnet to stroke on a non - magnetic material for awhile (like 10 minutes) and see what happens
the magnet gets weaker
If you drop a magnet it will hit the object under it
the nail goes to the magnet
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
When a magnet touches copper, there is no attraction or repulsion between them. This is because copper is not a magnetic material, so it does not interact with the magnetic field produced by the magnet.
it will loose its magnesium
When you rub a magnet with metal, the metal object becomes temporarily magnetized. This happens because the atoms in the metal align with the magnetic field of the magnet. However, once the magnet is removed, the metal object loses its magnetism.
Nothing.
dissaipates
stick it
it attracts
