A coil having an area `A_(0)` is placed in a magnetic field which changes from `B_(0)` to `4B_(0)` in a time interval `t`. The e.m.f. induced in the coil will be

A

`(3A_(0)B_(0))/(t)`

B

`(4A_(0)B_(0))/(t)`

C

`(3B_(0))/(A_(0)t)`

D

`(4B_(0))/(A_(0)t)`

Text Solution

Verified by Experts

The correct Answer is:
A
`e=-(dvarphi)/(dt)=(-3B_(0)A_(0))/(t)`
