A circular coil of 1000 turns each with area 1 m2 is rotated about its vertical diameter at the rate of one revolution per second in a uniform horizontal magnetic field of 0.07 T. The maximum voltage generation will be _____ V.

Solution

Given, N=1000, A=1 m2 and B=0.07 T

The maximum emf generated is εmax=NBAω,

=NBA2πf

 =1000×0.07×1×2π1=140π

Thus, maximum emf is 439.6 V≈440 V.
