State the characteristics of magnetic force.

(N/A) The following are the characteristics of magnetic force:
$(i)$ Magnetic force acts only on moving charges and not on stationary charges.
$(ii)$ No magnetic force acts on a charge if it is moving parallel or anti-parallel to the direction of the magnetic field.
$(iii)$ The direction of magnetic force is perpendicular to both $(a)$ the velocity vector of the charge and $(b)$ the magnetic field vector.
$(iv)$ The magnitude of magnetic force $(F)$ depends on the charge $(q)$,velocity $(v)$,and the strength $(B)$ of the magnetic field; i.e.,$F = qvB \sin \theta$,where $\theta$ is the angle between velocity and magnetic field.
$(v)$ The magnetic force $(F)$ acting on a current-carrying conductor of length $(L)$ placed in a magnetic field $(B)$ is given by $F = BIL \sin \theta$,where $I$ is the current flowing through the conductor.
