A conductor of length 2m carries a current of 0.8A while kept in a magnetic field of magnetic flux density 0.5T. The maximum force acting on it is?

A. 0.2N
B. 0.8N
C. 3.2N
D. 8.0N

Correct Answer:

Option B – 0.8N

Explanation

The force on the conductor is maximum when the conductor lies perpendicular to the field during which the maximum force is given as;
F = ILB = 0.8 x 2 x 0.5 = 0.8N
