No
a temporary magnet can be created by an electromagnet but it can also be created by any type of strong magnet
An unmagnetized magnet is not a magnet. A magnet remains a magnet only as long as it remains magnetic,and ceases to be a magnet when its magnetization is lost.Be that as it may in any event, the state of magnetization of a sample of magnetic material, whether magnetizedor unmagnetized, has no bearing, neither ball nor thrust, on the weight of the magnetic material. In other words,weight is invariant under a transformation of the magnetized state.
magnetism
The process by which a iron piece touching a permanent magnet behaves as a magnet as long as it maintains contact is called magnetic induction. not only does this work when the iron is physically touching the magnet but it works as long as the piece of iron remains under the influence of the magnet. A iron piece attracted to a magnet through a paper with out any physical contact will also behave as a magnet.
knife shows magnetic property when it remains physically contact with magnet for sometime.this type is known as temporary magnet
A permanent magnet.
No
the ground
a temporary magnet can be created by an electromagnet but it can also be created by any type of strong magnet
Lodestone is an example of a natural magnet.
A dumbbell shaped magnet is called which type of magnet?

An electro-magnet would be the strongest magnet. Or the sun itself would be the strongest natural magnet.
a permanent magnet does that.
Lodestone is the only example of a natural magnet.
the ones that attract stuff
