A charged particle moves with a velocity \( \vec{v} \) in a uniform magnetic field \( \vec{B} \). The magnetic force experienced by the particle is:
(A) never zero.
(B) always zero.
(C) zero, if \( \overrightarrow{\mathrm{B}} \) and \( \vec{v} \) are parallel.
(D) zero, if \( \overrightarrow{\mathrm{B}} \) and \( \vec{v} \) are perpendicular.
