Question

Kamla peddles a stationary bicycle, the pedals of which are attached to a 100 turn coil of area `0.10 m^(2)`.The coil rotates at half a revolution in one 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 ?

Answer 1

Here ν = 0.5 Hz, N =100, A = 0.1 `m^(2)` and B = 0.01 T. Employing Eq. (6.21)
`epsi_(0)=NBA(2piv)`
`=100xx0.01xx0.1xx2xx3.14xx0.5`
`=0.314 V`
The maximum voltage is 0.314 V.
We urge you to explore such alternative possibilities for power generation.
