Kamla peddles a stationary bicyle, the pedals of the bicycle are attached to a 100 turns coil of area `0.10m^(2)`. The coil rotates at half a revolution per second and it is placed in a uniform magnetic field of 0.01T perpendicular to the axis of rotation of the coil. What is the maximum voltage generated in the coil.

Explanation

Here f=0.5Hz, N=100, A=0.1 `m^(2)` and B=0.01T from the equation `epsilon=epsilon_(0) sin omega t= NBA omega sin omega t` maximum emf `epsilon_(0)= NBA omega = NBA(2 pi f)`
`epsilon_(0) = 100 xx 0.01xx0.1xx2 xx 3.14 xx 0.5 = 0.314 V`
