The length of a square coil’s side (l) is 0.1 m.
The current flowing through the coil (I) has a magnitude of 12 A.
The number of coil turns (n) is 20.
The angle formed by the coil’s plane with B (Magnetic field),
The magnetic field strength (B) is 0.8 T.
The magnitude of the magnetic torque experienced by the coil in the magnetic field is given by the following relationship:
Where,
A = Area of the square coil
= 0.1 x 0.1 = 0.01
So,
= 0.96 N m
As a result, the magnitude of the torque experienced by the coil is 0.96 N m.
