electromagnetic potentials

Mathematics

Maxwell’s equations can be simplified by defining an electric scalar potential φ‎ and a magnetic vector potential A in terms of which E, the electric field, and B, the magnetic field, can be expressed. A and φ‎ are given by

$B = \nabla \times A and E = - \nabla φ - \frac{1}{c} \frac{\partial A}{\partial t}$

where c is the speed of light. A and φ‎ are not uniquely determined by these expressions, and they are normally chosen to satisfy the extra condition $▽ . A + \frac{1}{c} \frac{\partial φ}{\partial t} = 0$ .
