A big circular coil of 1000 turns and average radius 10 m is rotating about its horizontal diameter at 2 rad s -1 . If the vertical component of earth's magnetic field at that place is 2 x 10 -5 T and electrical resistance of the coil is 12.56 
, then the maximum induced current in the coil will be
Text Solution
Verified by ExpertsThe correct answer is:
Given that,
Number of turns, N = 1000
Radius, r =10 m
Area, A = 
r 2 = 
x(10) 2
Earth's magnetic field strength, B = 2x10 -5 T
Resistance, R = 12.56 
Now,
=1A
