In the figure shown, the magnetic induction at the centre of the arc due to the current in portion `AB` will be

A

`(mu_(0)i)/r`

B

`(mu_(0)i)/(2r)`

C

`(mu_(0)i)/(4r)`

D

zero

Text Solution

Verified by Experts

The correct Answer is:
D
the magnetic induction at `O` due to the current in portion `AB` will be zero because `O` lies on `AB` when extended.
