Problem

A circular loop of radius 10 cm carries a current of 6 A. Through the centre of the loop, a straight conductor of length 10 cm is positioned so that it makes an angle of 30∘30^{\circ} with the magnetic field at the centre. The conductor carries 4 A. What is the magnitude of the force on the conductor? (a) 3.8×10−6 N3.8\times10^{-6}\,\text{N} (b) 2.4×10−6 N2.4\times10^{-6}\,\text{N} (c) 7.5×10−6 N7.5\times10^{-6}\,\text{N} (d) 1.5×10−5 N1.5\times10^{-5}\,\text{N}
