A circular coil of radius 2.0 cm ahs 500 turns in it and carries a current of 1.0 A. Its axis makes an angle of 30° with the uniform magnetic field of magnitude 0.40 T that exist in the space. Find the torque acting on the coil.
Given-
No. of turns of the coil, n = 500
Magnetic field intensity, B = 0.40 T = 4 × 10−1 T
Radius of the coil, r = 2 cm = 2 × 10−2 m
Magnitude of current, i = 1 A
Angle between the area vector and magnetic field, θ = 30°
Torque acting on the coil,
Where
B= applied magnetic field
A= area of rectangular loop
I = current flowing through coil
= angle between the area vector and magnetic field
