According to the Lorentz Force Law, the magnetic force on a moving particle with charge q and velocity v moving through a magnetic field B, is given by:
[tex]\vec{F}=q\vec{v}\times\vec{B}[/tex]
To find the direction of the force using the right hand palm rule, align your palm with the direction of v and then close your palm towards the direction of B. The direction where your thumb points will be the same direction that the force F has.
