Find the magnetic induction at point `O` if the current carrying wire is in the shape shown in the figure.
.

A

`(mu_(0)I)/(2R)`

B

`(mu_(0)I)/(2piR)`

C

`(mu_(0)I(pi^(2)+4)^(1//2))/(4piR)`

D

`(mu_(0)I(pi^(2)+4))/(4piR)`

Text Solution

Verified by Experts

The correct Answer is:
3
`B_(1)=(mu_(0)i)/(4pir)+(mu_(0)i)/(4piR),B_(2)=(mu_(0)i)/(4R),B=sqrt(B_(1)^(2)+B_(2)^(2))`
