Write an expression in a vector form for the Lorentz magnetic force `vecF` on a charge Q moving with velocity `vecV` in a magnetic field `vecB`. What is the direction of the magnetic force?

Explanation

The Lorentz magnetic force is given by the following relation:
`vecF=q vecVxx vecB`. Here q is the magnitude of the moving charge.
The direction of the magnetic force is perpendicular to the plane containing the velocity vector `vecV` and the magnetic field vector `vecB.`
