When the current is perpendicular to the magnetic field.

Vedclass · Answer

(B) The force $F$ on a current-carrying conductor in a magnetic field is given by the formula $F = BIl \sin(	heta)$,where $B$ is the magnetic field strength,$I$ is the current,$l$ is the length of the conductor,and $	heta$ is the angle between the direction of the current and the magnetic field.Since the maximum value of $\sin(	heta)$ is $1$ (which occurs when $	heta = 90^{\circ}$),the force is largest when the direction of the current is perpendicular to the direction of the magnetic field.

When is the force experienced by a current-carrying conductor placed in a magnetic field largest?
