Question

For the current carrying solenoid as shown below, draw magnetic field lines and giving reason explain that out of the three points A, B and C at which point the field strength is maximum and at which point it is minimum.

Answer 1

A solenoid is a coil of insulated or enameled wire wound on a rod-shaped form made of solid iron, solid steel, or powdered iron. Devices of this kind can be used as electromagnets, as inductors in electronic circuits, and as miniature 

Answer 2

Hi ,

Here is the magnetic field lines shown here below for the given current carrying solenoid .

Look as the field strength is maximum at the inside part of a solenoid as the number of field lines are very dense and the field at the outside is minimum as the field lines are less dense outside the solenoid .

Therefore here the magnetic field is maximum at the point A and minimum at the point B .

Hope it helps you .
