Question

In a solenoid carrying current, where is the magnetic field (i) maximum (ii) minimum and (iii) half of the maximum value?

Answer 1

A solenoid carrying current has (i) maximum value of magnetic field at a point will inside the solenoid lying on the axis of solenoid.
(ii) There is a minimum value of magnetic field at a point outside the solenoid near the middle of solenoid and (iii) half of the maximum value at a point near the end of the solenoid.
