Question

A wire carrying a current $I$ is placed in a uniform magnetic field in the form of the curve $y=a \sin \left(\frac{\pi x}{L}\right) \cdot 0 \leq x \leq 2 L$. The force acting on the wire is

Professor PC Thomas Classes · Answer

The total magnetic force on a curved wire carrying current in a uniform magnetic field depends only on the straight line distance between its ends.
