Question

The coil of an ac generator has 50 loops and a cross-sectional area of LaTeX: 0.2~m^20.2 m 2 . What is the maximum emf that can be generated, if the generator is spinning with an angular speed of LaTeX: 5.0~rad/s5.0 r a d / s in a LaTeX: 2.0~T2.0 Tmagnetic field

Answer 1

Maximum emf in the coil is 100 volt

Step-by-step explanation:

We have given number of loops in the coil N = 50

Cross sectional area
`A=0.2m^2`

Angular speed is given
`\omega =5rad/sec`

Magnetic field is given
`B=0.2T`

We have to find the maximum emf in the coil

Maximum emf in the coil is given by
`e=NBA\omega`

`e=50* 2* 0.2* 5=100volt`

So maximum emf induced in the coil is 100 volt
