Only moving charges experience force in a magnetic field. i.e.,on moving ,a charge q,with velocity v ,experiences a force in the presence of electric field(E) and magnetic field (B).
It can be represented as F= q(v x B)~(Ftotal=Felectricfield + Fmagneticfield )
Force acts perpendicular to both magnetic field and velocity of the electron.
Its direction is given by right hand thumb rule or screw rule.
The magnetic force is zero if charge is not moving, since lvl=0.
