Question

A loop of wire of 25 turns has an area of 2.0x10-2 m2. A current of 1.25A flows in the loop. Calculate the torque on the loop when its plane is PARALLEL to a uniform magnetic field of 0.2T.
Options
A 4.10 x 10-1 Nm
B 3.26 x 10-1 Nm
C 2.47 x 10-1 Nm
D 1.25 x 10-1 Nm
Correct Answer
Correct Answer

Option D is the correct answer.

Detailed Explanation

Plane parallel to B means maximum torque: tau=NBIA=(25)(0.2)(1.25)(0.02)=0.125Nm.

Hint

Plane parallel to B means maximum torque: tau=NBIA=(25)(0.2)(1.25)(0.02)=0.125Nm.
