A copper rod of length 
is rotated about one end perpendicular to the magnetic field 
with constant angular velocity 
. The induced e.m.f. between the two ends is
A
B
C
D
Text Solution
Verified by ExpertsThe correct answer is:
A
If in time 
. the rod turns by an angle 
, the area generated by the rotation of rod will be 
So the flux linked with the area generated by the rotation of rod
