Parallel to the magnetic field

Vedclass · Answer

(A) The magnetic force $F$ acting on a current-carrying wire of length $L$ carrying current $I$ in a magnetic field $B$ is given by the formula: $F = I L B \sin(	heta)$,where $	heta$ is the angle between the direction of the current and the magnetic field.For the magnetic force to be zero $(F = 0)$,the value of $\sin(	heta)$ must be zero.This occurs when $	heta = 0^{\circ}$ or $	heta = 180^{\circ}$.Therefore,when the current-carrying wire is placed parallel to the magnetic field,the magnetic field does not exert any force on it.

How is a current-carrying wire placed in a magnetic field so that the magnetic field does not act on it?
