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
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
