Question

A boy peddles a stationary bicycle the pedals of the bicycle are attached to a 200 turn 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 0.02 T perpendicular to the axis of rotation of the coil. The maximum voltage generated in the coil is
A. `1.26V`
B. `2.16V`
C. `3.24V`
D. `4.12V`

Answer 1

Correct Answer - A
Here, `v=0.5 Hz. N=200,A=0.1m^(2)`
and `B=0.02T`
Maximum voltage generated is
`epsi_(0)NBA(2piv)=200xx0.02xx0.1xx(2pixx0.5)=1.25V`
