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∘ with the magnetic field at the centre. The conductor carries 4 A. What is the magnitude of the force on the conductor?
a) 3.8×10−6N
b) 2.4×10−6N
c) 7.5×10−6N
d) 1.5×10−5N
