Question

what do you mean by solenoid ​

Answer 1

Explanation:

A solenoid is a long coil of wire wrapped in many turns. When a current passes through it, it creates a nearly uniform magnetic field inside.

Solenoids can convert electric current to mechanical action, and so are very commonly used as switches.

The magnetic field within a solenoid depends upon the current and density of turns.

In order to estimate roughly the force with which a solenoid pulls on ferromagnetic rods placed near it, one can use the change in magnetic field energy as the rod is inserted into the solenoid
