3.2 Charge in a uniform magnetic field
The action of a magnetic field on a charged particle is given
by the force law:
This force manifest very peculiar characteristics due
to two reasons:
The basic effect upon a charged particle is due to the component
of the velocity normal to the magnetic field, which generates a circular
motion in the plane perpendicular to B, without changing the component
of the velocity along B.
It depends on the velocity of the particle
It makes no work upon the particle, as F.v=0.
As a consequence, the kinetic energy of the particle remains constant
