An iron core and copper wire (that is coated with an insulator) are used all the time to make electromagnets.
The role of an electromagnet is to provide us withrecycled materials. The electromagnet is what picks up our heavy metal bits and bobs and moves it or drops it from a certain height so that the metal breaks and can be used again to make another car .
In an electromagnet, the negative side of the coil is said to "emit" the magnetic field lines- it is the north pole of the electromagnet. However, in alternating current, the energized wire alternates between positive and negative. As a result, a conventional electromagnet running on alternating current would constantly be undergoing a reversal of the poles.
I'm not sure where a bar magnet is used, but an electromagnet is used in junkyards, and in some laboratories.
Electro Magnetic is correct
An electromagnet is used.;)
