force on moving charge

Question

Magnetic force on charge q moving with velocity v in field B is proportional to:

RankGuru · Accepted Answer

A point charge $q$ moving with velocity $\vec{v}$ in a magnetic field $\vec{B}$ experiences a **Lorentz force**:
$\vec{F} = q(\vec{v} 	imes \vec{B})$
- In magnitude: $F = q v B \sin 	heta$
- $	heta$ is the angle between $\vec{v}$ and $\vec{B}$.
- The force is always perpendicular to both $\vec{v}$ and $\vec{B}$.
- If $\vec{v}$ is parallel to $\vec{B}$ ($	heta=0^\circ$), $F = 0$.
