A coil of 50 turns has dimensions `10 times 10cm` It is rotated at the rate of 5 r.p.s in a uniform magnetic field of flux density 0.7 T. The max. emf induced in it is :

A

8V

B

11V

C

15V

D

19V

Text Solution

Verified by Experts

E=NBA `omega sin omega =2pi f=220/7 s^-1`
`E_(max)= NBA omega=50 times 0.7 times 100 times 10^-4 times 220/7=11V`
