Aflat 145-turn current-carrying loop is immersed in a uniform magnetic field. the area of the loop is 6.75 cm2 and the angle between its magnetic dipole moment and the field is 31.5°. find the strength of the magnetic field that causes a torque of 1.33 × 10-5 n·m to act on the loop when a current of 2.11 ma flows in it.

The magnetic field strength created around the loop is 0.123 T.

The given parameters;

The torque on the loop is calculated as follows;

Where;

B is the magnetic field strength

Thus, the magnetic field strength created around the loop is 0.123 T.

Magnetic field, B = 0.123 T

Explanation:

It is given that,

Number of turns in current carrying loop, N = 145

Area of the loop,

The angle between its magnetic dipole moment and the field is 31.5°

Torque,

Current,

Toque on the current carrying loop is given by :

B = 0.123 T

So, the strength of the magnetic field is 0.123 T. Hence, this is the required solution.
