Question

the force exerted by a current carrying conductor placed in a magnetic field is zero when the angle between wire and the magnetic field is

(a) 60 degree

(b) 90 degree

(c) 0 degree

(d) 45 degree​

Answer 1

Answer:

option (c) 0 degree is right option

Explanation:

The angle between the wire and the direction of the magnetic field is 180°

For a current-carrying wire, force is the is felt in the presence of an external magnetic field. Using the formula,

F = BILsinӨ, where,

L is the length of the wire

I is the current

Ө is the angle between the current direction and the magnetic field

We know that sin 180° is 0. Therefore, the force exerted on a current-carrying wire that is placed in a magnetic field is zero.
