Pitch angle

pitch angle
(Science: physics) For a charged particle moving in a magnetic field, this is the angle arctan (v-perp/v-parallel), where v-parallel is the component of the particle’s velocity parallel to the magnetic field, and v-perp is the perpendicular component. The pitch angle is zero when the particle moves purely parallel to the field, and 90-degrees when the particle has no parallel velocity at all.
