Lorentz force formula : Force experienced by a charged particle (charge q) moving in a magnetic field B with a velocity v is given by : F = q(v X B) where F is the force vector, v is the velocity vector and B is the magnetic field vector.
Magnitude of the force is given by F = qvBsinθ where θ is the angle between the vectors v and B. Direction of the force vector is given by the direction rule of vector (cross) multiplication of two vector say A and B which states as follows :
A
