In the given loop the magnetic field at the centre O is

A

`(mu_(I))/(4)((r_(1)+r_(2))/(r_(1)r_(2)))` out of the page

B

`(mu_(0)I)/(4)((r_(1)+r_(2))/(r_(1)r_(2)))` into the page

C

`(mu_(0)I)/(4)((r_(1)-r_(2))/(r_(1)r_(2)))` out of the page

D

`(mu_(0)I)/(4)((r_(1)-r_(2))/(r_(1)r_(2)))` into the page

Text Solution

Verified by Experts

The correct Answer is:
B
`B=B_(1)+B_(2)=(mu_(0)i)/(4r_(1))+(mu_(0)i)/(4r_(2)),B_("total")=(mu_(0)I)/(4)((r_(1)+r_(2))/(r_(1)r_(2)))`
