Question

A charge q enters perpendicularly with the direction of a magnetic field $\overline{B}$ with a velocity $\overline{V}$. What would be the force acting on this charge?

Answer 1

The force acting on the particle moving perpendicularly in a magnetic field would be given by the vector $\overrightarrow{F}=q(\overrightarrow{v}\times \overrightarrow{B})$

This is called the magnetic part of the Lorentz force.
