Question

The strength of the magnetic field inside a long current carrying solenoid is:

  1. More at the ends than at the centre
  2. Minimum in the middle
  3. The same on all points
  4. Found to increase from one end to the other

hintHint:

The magnetic field lines inside a current carrying solenoid are parallel and equidistant

The correct answer is: The same on all points


    The magnetic field lines inside a current carrying solenoid are parallel and equidistant which means the strength of magnetic field is uniform inside the solenoid i.e. same at all points.
