# Lorentz Force

Written by Jerry Ratzlaff on . Posted in Electromagnetism

Lorentz force, abbreviated as F, is when you place a moving charged particle in a magnetic field.

## Lorentz Force formulas

 $$\large{ F = q \; v \; B }$$ (Lorentz force) $$\large{ F = I \; L \; B }$$ (straight current carrying wire that is not moving)

### Where:

 Units English Metric $$\large{ F }$$ = Lorentz force $$\large{T}$$ $$\large{T}$$ $$\large{ I }$$ = current in the wire $$\large{I}$$ $$\large{I}$$ $$\large{ q }$$ = electric charge $$\large{C}$$ $$\large{C}$$ $$\large{ L }$$ = length of the wire that is in the magnetic field $$\large{ft}$$ $$\large{m}$$ $$\large{ B }$$ = magnetic field $$\large{T}$$ $$\large{T}$$ $$\large{ v }$$ = speed of moving charge $$\large{\frac{ft}{sec}}$$ $$\large{\frac{m}{s}}$$
