Assume that the loop is initially positioned at θ=30∘θ=30∘ and the current flowing into the loop is 0.500 AA . If the magnitude of the magnetic field is 0.300 TT , what is ττtau, the net torque about the vertical axis of the current loop due to the interaction of the current with the magnetic field?

Torque,

Explanation:

Given that,

The loop is positioned at an angle of 30 degrees.

Current in the loop, I = 0.5 A

The magnitude of the magnetic field is 0.300 T, B = 0.3 T

We need to find the net torque about the vertical axis of the current loop due to the interaction of the current with the magnetic field. We know that the torque is given by :

Let us assume that,

is the angle between normal and the magnetic field,

Torque is given by :

So, the net torque about the vertical axis is . Hence, this is the required solution.
