Explanation:An electromagnet is a magnet that runs on electricity. Unlike a permanent magnet, the strength of an electromagnet can easily be changed by changing the amount of electric current that flows through it. The poles of an electromagnet can even be reversed by reversing the flow of electricity.

$\fbox \color{blue} Required\: Answer:-$

➢ Electromagnets are made out of a coil of wire (wire curled in series). This is more effective in producing a magnetic field than just a wire running straight. This effect can be strengthened by winding a wire tightly around a powerful core, made of magnetic material, such as iron.

➢ Some electromagnet uses are given in the points mentioned below:

• Particle Accelerators
• Amplifiers
• Magnetic Separation
• Electric Motors and Generators
• MRI machines
• Control Switches in Relays
• Transportation
• Spacecraft Propulsion Systems
• Induction Heating
• Hard Drives
