Interesting question. The answer is maybe - it depends on the construction of the electromagnet. the key is the electromagnet must be water proof, and the wiring used to create the magnet must be insulated from water - if this is not done, then current will flow through the water, which will decay the effectiveness of the electromagnet, along with robbing it of strength due to a decrease in current through the magnet.
Yes, a magnet will work under water. To cite one example, a magnet on a string out on the docks is sometimes used to retrieve car keys that tourists sometimes accidently drop into the water.
No. You'll end up with two smaller magnets, and each will have less than half the magnetic field strength of the original magnet.
Yes, using a magnet or wind or water.
A strong magnet or electromagnet can be used to hold the iron oxide(rust) in place as the water is poured off. Care should be taken to bring all of the rust near the magnet in order to collect it all.
A permanent magnet may become unmagnetized because a shock it will have.
Yes, a magnet can still pick up a paper clip even when both are under water because water does not significantly affect the magnetic force between the magnet and the paper clip.

no
---- Magnetism can be destroyed by following methods:---- * By heating the magnet, * By hammering the magnet.--->In accordance to this point...allowing the magnet to fall violently* By keeping similar poles of magnets together for a long time. * [not sure about this]by keeping magnet under running water.
magnets dont lose their magnetism under water. According to me magnets do attract paper under water.
Yes. Water is diamagnetic, but it impedes a magnet's strength only very slightly, not to a significant degree.
If you drop a magnet it will hit the object under it
I think if you put a magnet in a liquid i think it is not going to work again. I think if you put a magnet in a liquid i think it is not going to work again.

Yes, a magnet can float on a cork in water because the cork provides buoyancy to keep the magnet afloat. The buoyant force of the water supports the weight of the cork and the magnet, allowing them to float together.
No
The magnet should be able to extract iron out of water as water and iron are not chemically combined. If the water and iron would have chemically combined then it would be futile to separate them using a magnet. Note that the stronger the magnet the more iron will be removed from water.
