# Problem: What is the shape of the trajectory that a moving charged particle follows in a uniform magnetic field?

###### FREE Expert Solution

Magnetic force on a moving charge:

$\overline{){\mathbf{F}}{\mathbf{=}}{\mathbf{q}}{\mathbf{v}}{\mathbf{B}}{\mathbf{s}}{\mathbf{i}}{\mathbf{n}}{\mathbf{\theta }}}$

The path followed depends on the angle θ.
