The current flows from A to B as shown in the figure. What is the direction of current in circle?

A

Clockwise

B

Anti-clockwise

C

Straight line

D

None of these

Text Solution

Verified by Experts

The correct Answer is:
D
As magnetic field through circle is constant because current through straight wire is constant. Magnetic flux through circle is not changing with time.
`(dphi_(B))/(dt)=0`
`rArr" "|E|=|(dphi_(B))/(dt)|=0rArri=(E)/(R)=(0)/(R)=0`
