Question

explain what is solenoid

Answer 1

A solenoid is a type of electromagnet when the purpose is to generate a controlled magnetic field. If the purpose of the solenoid is instead to impede changes in the electric current, a solenoid can be more specifically classified as an inductor rather than an electromagnet.

Answer 2

Solenoid

A long cylindrical coil consisting of a large number of turns of insulted wire is called solenoid. When some electric current flows through the solenoid, It behave like bar magnet.

• When current increase, magnetism also increases.

• The magnetic line of force are parallel near the center of coil. Thus produced magnetic field is said to be uniform.

• The magnetic line of force are in same direction within the space enclosed by the coil.

• The magnetic lines of force are at right angle to the plane of the coil.
