Moving charged particles in a magnetic field

- Recall the motor effect. If a current passes through a magnetic field it experiences a force.
- As a current is just charge over time ($I = \frac{q}{t}$), a
**charge moving**in a**magnetic field**would also**experience a force**.

- This force's direction can be found by the
**Right-Hand rule.** - As such,
**only the perpendicular component**of the partice's motion is taken into account. - Thus, mathematically, this force can be defined as:

\begin{align} F = qvB\sin{\theta} \end{align}

Where:

- $F$ is the
**force**on the particle. (N) - $q$ is the
**charge**on the particle (C) - $v$ is the
**velocity**that the proton is travelling ($ms^{-1}$) - $B$ is the
**magnetic field strength**(T) - $\theta$ is the
**angle between the direction**of the charged particle**and the magnetic field.**
