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

Verified by Experts

Here f = 0.5Hz: N = 100, `A = 0.1m^2`
from the equation `epsi = epsi_0 sin omega t = NBA omega sin omega t`
maximum emf `epsi_0 = NBA omega = NBA(2pi f ) `
` epsi_0 = 100 xx 0.01xx0.1xx2 xx 3.14 xx 0.5 = 0.314V`
