The magnetic induction at centre O Fig.

A

`(mu_(0)I)/(2a)+(mu_(0)I)/(2b) ox`

B

`(3mu_(0)I)/(8a)+(mu_(0)I)/(8b) ox`

C

`(3mu_(0)I)/(8a)-(mu_(0)I)/(8b) ox`

D

`(3mu_(0)I)/(8a)+(mu_(0)I)/(8b) ox`

Text Solution

Verified by Experts

The correct Answer is:
B
`B=3/4[(mu_(0)I)/(2a)]+1/4[(mu_(0)I)/(2b)]`
`B=(3mu_(0)I)/(8a)+(mu_(0)I)/(8b)`
