Question

What is the magnitude of magnetic force per unit length on a wire carrying a current of 8 A and making an angle of 30 degrees with the direction of a uniform magnetic field of 0.15 T?

Professor PC Thomas Classes · Answer

Force per unit length $f = IB \sin	heta = 8 	imes 0.15 	imes \sin(30^\circ) = 1.2 	imes 0.5 = 0.6	ext{ N/m}$.
