Lorentz force
- almost all forces in mechanics are conservative forces, those that are functions nly of positions, and certainly not functions of velocities
- Lorentz force is a rare example of velocity dependent force
polarization of light
- has two possibilites
- what does this mean?
Maxwell's equations
Covariant formulation
electromagnetic field
- an example of four-vector
- gague field describing the photon
- composed of a scalar electric potential and a three-vector magnetic potential
four-current
- charge density and current density
- http://en.wikipedia.org/wiki/Four-current
\[J^a = \left(c \rho, \mathbf{j} \right)\]
where
- c is the speed of light
- ρ the charge density
- j the conventional current density.
- a labels the space-time dimensions
four vector potential
- this is what we call the electromagnetic field
