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.
no it is magnetism
Magnetism
Either the water is too hot or too cold it needs to be room temperate
If you hold a nail or a paperclip near the coil it will attract because of the magnetism.
The nail will rust.
banging the magnet makes the 'mini-magnets' inside the big magnet go back to the way they were before magnetism. xx
This would be magnetism.

Rubbing a nail with a magnet will align some of the magnetic domains in the nail. This will have the effect of making the nail into a magnet. The nail won't be a strong magnet, but it will come away with some residual magnetism. Suggestion: try a simple experiment with a nail and a magnet and some small paper clips to see if this works.
The nail is made of non-polarized iron. and doesn't repel either side of a magnet. A magnet has two poles and will repel another magnet with the same pole (north repels north, south repels south). Since the nail doesn't have a poles it doesn't repel either side.
A magnet which doesn't lose it's magnetic effect when it's away from another magnet .Steel magnets are usually permanent magnets , while those made of iron lose their magnetism , as soon as the original magnet is held away . I simply mean that :-For example , when you use a magnet to attract a paperclip ( or a nail ) made of iron , and you attach a second paperclip to the first one , while still holding the first one to the magnet , the 2nd will still be held to the 1st .As soon as you remove the magnet , the magnetism between the 1st and the 2nd clips will be broken down , and they will fall down .But if you use nails ( or paperclips ) made of steel , the magnetism between the 1st and the 2nd nail will still be there , even if the original magnet is held away from the 1st .
