• GP Magnetism

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

1. more at the ends than at the centre
2. minimum in the middle
3. same at all points
4. found to increase from one end to the other

Answer

Inside the solenoid, magnetic field lines are parallel to each other hence forming a uniform field strength which indicates that the magnetic field is the same at all points inside the solenoid.

The correct option is C.
