Inside a parallel plate capacitor the electric field E varies with time as `t^(2)`. The variation of induced magnetic field with time is given by

A

a) `t^(2)`

B

b) no variation

C

c) `t^(3)`

D

d) `t`

Text Solution

Verified by Experts

The correct Answer is:
D
Varying electric field induces magnetic field and this induced magnetic field is proportional to the rate of change in electric field. According to the question, electric field is proportional to `t^(2)and(d)/(dt)(t^(2))=2t`, so induced magnetic field is proportional to t.
