Question

What is the force experienced by a moving charge in a magnetic field?

Answer 1

A charge moving with velocity \[[\vec{v}]\] in a magnetic field \[[\vec{B}]\] experiences the magnetic Lorentz force \[[\vec{F}=q(\vec{v}\times\vec{B})]\]. Its magnitude is \[[F=|q|vB\sin\theta]\], where \[[\theta]\] is the angle between \[[\vec{v}]\] and \[[\vec{B}]\]. The force is perpendicular to both the velocity and the magnetic field.
