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

Answer:

Maximum emf in the coil is 100 volt    

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 $e=NBA\omega$

$e=50\times 2\times 0.2\times 5=100volt$

So maximum emf induced in the coil is 100 volt
