A copper rod of length 'l' m is rotated about the end perpendicular to a uniform magnetic field of flux density 'B' with constant angular velocity 'ω'. The induced e.m.f. between the two ends is:
A
B
C
D
Text Solution
Verified by ExpertsThe correct answer is:
D
If in time 't', the rod turns by the angle 'θ', the area generated by the rotation of the rod will be:
So, the flux linked with the area generated by the rotation of the rod:
The induced EMF is:
