Choose the correct option.
The magnetic field inside a long straight solenoid-carrying current
(a) is zero.
(b) decreases as we move towards its end.
(c) increases as we move towards its end.
(d) is the same at all points.
The magnetic field inside a long straight solenoid-carrying current is Uniform in nature, So the magnetic field is the same at all points.
Hence option (d) is correct Answer
