A uniform but time varying magnetic fiel...

A uniform but time varying magnetic field `B=(2t^3+24t)T` is present in a cylindrical region of radius `R =2.5 cm` as shown in figure.

In the previous problem, the direction of circular electric lines at `t=1 s` is

A

clockwise

B

anti clociwise

C

no current is induced

D

cannot be predicted

Text Solution

Verified by Experts

The correct Answer is:
B
`ox` Magnetic field is increasing. Hence `o.` magnetic field is produced b a conducting circular loop placed there. For producing magnetic field induced current should be anti clockwise.
Direction of induced circular electric lines are also anti clockwise.
