helical motion: The motion that is
produced when one component of the
velocity is constant in magnitude and
direction (i.e., straight-line motion)
while the other component is constant
in speed but uniformly varies in
direction (i.e., circular motion).

helical motion
(noun)

The motion that is produced when one component of the velocity is constant in magnitude and direction (i.e., straight-line motion) while the other component is constant in speed but uniformly varies in direction (i.e., circular motion). It is the superposition of straight-line and circular motion.

Helical Motion
Helical motion results when the velocity vector is not perpendicular to the magnetic field vector.
In the section on circular motion we described the motion of a charged particle with the magnetic field vector aligned perpendicular to the velocity of the particle.
This produces helical motion (i.e., spiral motion) rather than a circular motion.
Uniform circular motion results.

Direction of the Magnetic Force: The Right Hand Rule
Because the force is always perpendicular to the velocity vector, a pure magnetic field will not accelerate a charged particle in a single direction, however will produce circular or helical motion (a concept explored in more detail in future sections).
