Hint: An electromagnet is a kind of magnet in which the magnetic field is generated by an electric current. The electromagnets generally consist of wire wound into a coil. A current through the wire produces a magnetic field which is intensified in the hole, denoting the centre of the coil.

Complete step by step solution:
Electromagnets are extensively utilized as integrands of other electrical devices, instance motors, generators, electromechanical solenoids, relays, loudspeakers, hard disks, MRI machines, scientific instruments, and magnetic separation equipment. Electromagnets are also used in industry for picking up and moving heavy iron objects such as scrap iron and steel.

Generators:
Generators are basically running on the linkage between magnetism, motion and electricity. Generators usually use an electromagnet, which is generated by electricity and a continuously rotating turbine to produce large quantities of current. The regular generator contains a group of enclosed wire coils in the shape of a cylinder. Inside the cylinder there is a spinning electromagnet.

Relay:
A relay is also an electromagnetic switch which is used to switch High Voltage or Current by using low power circuits. For instance, we can use it for managing home devices with a normal low voltage electronic circuit. Electromagnetic relays use an electromagnet to operate a switching device mechanically.

Note: Some of the disadvantages of Electromagnetism is that Electromagnets heat up very fast, It takes a large amount of energy to use, If turned up too high it could be dangerous, There is a type of radiation that comes from electromagnetism, and these types of radiation are showed in the electromagnetic spectrum.
