Answer 1

here,

radius , r = 65 cm = 0.65 m

magnetic feild , B = 5.85 * 10^-5 T

theta = 45 degree

current , I = 95 A

the magnitude of torque on the loop , T = N * I * A * B * sin(theta)

T = 1 * 95 * pi * 0.65^2 * 5.85 * 10^-5 * sin(45) N.m

T = 5.21 * 10^-3 N.m

the magnitude of torque on the loop is 5.21 * 10^-3 N.m
