A 300 Turn coil of area 25 cm2 is placed in an 80mT magnetic

A 300 Turn coil of area 25 cm2 is placed in an 80mT magnetic field. If the coil carries a current of 3.3 A, what isthe magnitude of the maximum magnetic torque it could experience?

Solution

Here ,

Number of turns , N= 300

area , A = 25 cm^2

magnetic field , B = 80 mT

current , I = 3.3 A

maximum magnetic torque = N * A * B * I

maximum magnetic torque = 300 * 25 *10^-4 * 0.080 * 3.3

maximum magnetic torque = 0.198 N.m

the magnitude of the maximum magnetic torque it could experience is 0.198 N.m
