The magnetic field inside a current carrying solenoid is
Decreases as we move towards its ends
Increases as we move towards its ends
Zero
Same at all points
The magnetic field produced by a current carrying solenoid is same at all points inside it.
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.
Question 3 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
From above fromula we can say, magnetic field due to a current carrying toroidal solenoid is independent of its radius.The magnetic field at the ends of a solenoid is
