Answer:
An electromagnet is a coil of wire wrapped around a bar of iron or other ferromagnetic material. When electric current flows through the wire, it causes the coil and iron bar to become magnetized. An electromagnet has north and south magnetic poles and a magnetic field.
Explanation:
The three main components of an electromagnet are the iron core, copper wire, and an electricity source.
An electromagnet is a magnet in which a coiled or wrapped wire is given electricity. When Current is given to this wire, it acts like a magnet. An electromagnet is used to create a magnetic field.
The three main parts of the electromagnet are the iron core, that is the magnet, which is a small round, or square brick-like. The wire, wire, is made up of copper. The electricity source, by which electricity is given to the electromagnet.
Examples of electromagnets are induction cookers, doorbell rings, etc. They are controllable and adjustable magnets and are used in most electric appliances.
Thus, the three parts are the iron core, copper wire, and an electricity source.
