Two circular loops of wire, each containing a single turn, have

the same radius of 5.3 cm and a common center. The planes of the

loops are perpendicular. Each carries a current of 1.8 A. What is

the magnitude of the net magnetic field at the common center?

field at the centre of circular loop = mu * I /2R

I = 1.8A , R = 0.053 m ,

hence ,

B = 4*3.14*10^-7 * 1.8 /(2*0.053)

B = 2.133*10*^-5 T ,

Field due to both these , will be at perpendicular .

hence ,

net B = B * sqrt 2 = 3.0163 *10^-5 T
