Question

What is a solenoid? what are the factors that affect the magnitude of magnetic field of solenoid? what is it's main use?​​

Answer 1

1. Solenoid is the generic term for a coil of wire used as an electromagnet.

2. Factors Affecting the Strength of the Magnetic Field of an Electromagnet: Factors that affect the strength of electromagnets are the nature of the core material, strength of the current passing through the core, the number of turns of wire on the core and the shape and size of the core.

3. Solenoids are most commonly used as electromagnets, and all the examples so far are that kind of solenoid. But there are some other uses. They can be used to slow the flow of electricity in a circuit, making them an example of an inductor, or an impedance device.
