when a charged particle moves in an external UNIFORM magnetic field then it experiences a magnetic force.
The magnetic force (
on a charge q moving with velocity
in a magnetic field 
is given both in magnetude and direction, by
on a charge q moving with velocity in a magnetic field is given both in magnetude and direction, by | = q( x ) |
Particle Motion under O Magntic Field:
(Secondary Information)
= q( + )
If change is projected
to the Magnetic Field. The path of the charged particle is purely circular and magnetic force povides necessary centripedal force.
R = Radius of the path.
T = Time period of the path.
Otherwise particle moves in a helical path:
Radius =
Time Period =
Pitch = V11 x T =

When it moves, the chg in its electric field will give rise to magnetic field which will affect the external magnetic field depending on the direction of its motion (and hence the direction of the induced magnetic field.)
A moving charged particle in an external magnetic field will experience a force given by F = q(v X B)
