A coil of `100` turns, each of area `0.02m^(2)` is kept in a uniform field of induction `3.5xx10^(-5)`T. If the coil rotates with a speed of `6000r.p.m.` about an axis in the plane of the coil and perpendicular to the magnetic induction, calculate peak value of e.m.f. indcued in the coil

Explanation

Given: `n=100`, `A=0.02m^(2)`, `B=3.5xx10^(-5)T`,
`f=6000 r.p.m=(6000)/(60)r.p.s. e_(max)=?`
Induced e.m.f. in a rotating coil,
`e=2pifBnAsinomegat`
`e_(max)=2pifBnA`
`=2pi(6000)/(60)xx3.5xx10^(-5)xx100xx0.02`
`=2xx(22)/(7)xx3.5xx2xx10^(-3)`
`=0.044` volt.
