Question

Magnetic Field due to a Solenoid​

Answer 1

Answer:

A solenoid is a coil of wire with electric current flowing through it, giving it north and south magnetic poles and a magnetic field. Using more turns of wire in the coil or more current increases the strength of the solenoid's magnetic field.

Answer 2

Answer :

When an electric current is passed through the solenoid, a magnetic field is produced around and within the solenoid. ... The lines of force inside the solenoid are nearly parallel which indicates that the magnetic field 'within' the solenoid is uniform and parallel to the axis of the solenoid.
