JEE MainPhysicsMagneticsMCQ+4 / −1
A uniform magnetic field of 2×10−3 T2 \times 10^{-3} \mathrm{~T}2×10−3 T acts along positive YYY-direction. A rectangular loop of sides 20 cm20 \mathrm{~cm}20 cm and 10 cm10 \mathrm{~cm}10 cm with current of 5 A5 \mathrm{~A}5 A is in Y−ZY-ZY−Z plane. The current is in anticlockwise sense with reference to negative XXX axis. Magnitude and direction of the torque is:
