#### Question

Write the expression, in a vector form, for the Lorentz magnetic force \[\vec{F}\] due to a charge moving with velocity \[\vec{V}\] in a magnetic field \[\vec{B}\]. What is the direction of the magnetic force?

#### Solution

The Lorentz magnetic force is given by the following relation:

`vecF=q(vecVxxvecB)`

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)`

Is there an error in this question or solution?
