In figure what is the magnetic field induction at point ‘O’?

A

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

B

`(mu_(0)i)/(4pir)+(mu_(0)i)/(2pir)`

C

`(mu_(0)i)/(4pir)+(mu_(0)i)/(4pir)`

D

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

Text Solution

Verified by Experts

The correct Answer is:
D
B at O due to three positions.
(A) vertical straight portion `to(mu_(0)i)/(4r)` zero. (B) semi-circular portion outward
(C) straight horizontal portion `to(mu_(0)i)/(4pir)` outward
