Question on: JAMB Physics - 2000
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
Ask EduPadi AI for a detailed answer
Correct Option: B
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
