One the the most important applications of the concepts you have learned are the equations which describe classical electricity and magnetism. When we set <math>\mathbf{E} \ </math> as the [[electric field]], <math>\mathbf{B} \ </math> as the [[magnetic field]], <math>\mathbf{D} \ </math> as the [[electric displacement field]], and <math>\mathbf{H} \ </math> as the [[magnetizing field]], then the equations describing these quantities are
