There are two concentric circular loops....

There are two concentric circular loops. One loop of radius r is made up of only one turn. The other loop has a radius 2r and has two turns of wire. They are arranged such that they have a common centre and their planes are perpendicular to each other. When the same current i is passed through both the coils, the magnetic field at the common centre is

A

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

B

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

C

`(mu_(0)i)/(2r) sqrt2`

D

zero
