PX157 - C1a - the lorentz force

magnetic field

force exerted by a magnetic field on a charge, $q$ , moving at velocity, $\vec{v} :$

\vec{F} = q \vec{v} \times \vec{B}

magnetic field (magnetic induction): $\vec{B}$
units: $t e s l a (T) = k g C^{- 1} s^{- 1}$
note:
- $\vec{F} ⊥ \vec{v} a n d \vec{B}$
- $\vec{F}$ is opposite for opposite charges
total lorentz force:

\vec{F} = q (\vec{E} + \vec{v} \times \vec{B})
