The force experienced by a charged particle moving in space where electric and magnetic field exists is called Lorentz force. When a charged particle carrying charge
q is subjected to an electric field of strength
, it experiences a forcegiven by
e=q whose direction is same as
or opposite of
depending on the nature of charge, positive or negative.
If a charged particle is moving in a magnetic field of strength
with a velocity
it experiences a force given by
m=q(×). The direction of this force is in the direction of
× i.e.perpendicular to the plane containing
and
is directed as given by right hand screw rule. Due to both the electric and magnetic fields, the total force experienced by the charge
q is given by
=e+m =q+q(×)
