whate is an electromagnet?
Answers
Answer:
An electromagnet can be defined as a magnet which functions on electricity.
Explanation:
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. The picture above shows a coil wound around an iron nail. On its own, the iron nail is not magnetic.
Answer:
Electromagnetism is a process where a magnetic field is created by introducing the current in the conductor.
When a conductor is electrically charged it generates magnetic lines of force of conductor.
For example, if current i.e., positive charges moving in a wire, it produces the magnetic field along the wire, and the direction of magnetic lines and force can be determined using Right-hand Rule.
