Physics Question on Magnetic Effects of Current and Magnetism

A square loop with each side 1 cm, carrying a current of 10 A, is placed in a magnetic field of 0.2 T. The direction of the magnetic field is parallel to the plane of the loop. The torque experienced by the loop is .
Fill in the blank with the correct answer from the options given below

A

zero

B

2×10−4Nm2 × 10^{-4} Nm

C

2×10−2Nm2 × 10^{-2} Nm

D

2Nm

Answer

zero

Explanation

Solution

When the magnetic field is parallel to the plane of the loop, no net torque is experienced by the loop. Torque depends on the angle between the magnetic field and the area vector of the loop.
