1.

A circular loop of radius 10 cm carries a current of 15A. At its center is placed a small loop of radius 1cm with 50 turns and a current of 1A. A) what is the B-vector of the magnetic field produced by the large loop at its center? (b) What is the H-vector of the field? (c) What torque acts on the small loop when its plane is perpendicular to the plane of the large loop?

Answer» Correct Answer - (a) `9.4 xx 10^(-5)`T, (b) 74.96 `Am69-1)`, © `1.5 xx 10^(-6)`Nm
