Magentic materials are mainly of three types. 1) Diamagnetic materials 2) Paramagnetic materials 3) Ferromagnetic materials Diamagnetic meterials are those that do not have megnetic property. Para magnets can be used as temporary magnets Ferro magnetic materials are tose which are permanent magnets. The magnets made from magnets that easily lose their magnetis catue are paramagnets.

An electro magnet proves that Electricity and Magnetism always co-exist in nature
Both are magnetic.
Magnetic forces are produced by the motion of charged particles such as electrons. Magnetism is one of the fundamental forces of nature.

The simple answer is, it becomes weaker and weaker and eventually looses its magnetism. In a permanent magnet magnetic domains within the material are nearly all oriented in the same direction, amplifying the magnetic effect. As one heats this material, the domains become more random. When heated sufficiently high, to the CURIE POINT, the material loses all of its magnetism. If the material is then cooled in the presence of a magnetic field, it will be re-magnetized. In some materials, heating to temperatures below the curie point will result in temporary loss of magnetism which will be regained as the material cools (reversible losses). Heating to temperatures below the curie point may also cause irreversible losses, ie, the magnetism does not return to its previous strength when cooled.
A magnet is produced by aligning the magnetic domains in a material to point in the same direction. When heated, the magnet loses its magnetism as the molecular motion, which is caused by heating, destroys the alignment of the magnetic domains. Ferromagnetic materials also lose its magnetism after being melted. However, when the magnet is being hammered whilst cooling in a magnetic field, the melted magnet would gain its magnetism again.
The known magnetism in a bar magnet is electromagnetism.
The main advantage of an electromagnet is it can be turned on and off. Iron is a soft magnetic material an therefore looses its magnetism very quickly, if you use a metal like like steel it will not loose it magnetism very easily and even if you turn off the current it will remain a magnet.
A magnet is a piece of iron or other material that attracts other iron-containing objects. The characteristic that exists in magnets that does not exist in materials that lack magnetism is the alignment of domains.
If one continously heats a particular magnet to high temperatures or long time or both, it loses it magnetism because the particles get excited and start forming no-magnetic arrangements.

A magnets magnetism is strongest at the poles.
No it wont but if the water is hot then it will lose its magnetism
