Ampere's law (a) write maxwell's equations in differential form in the absence of charges (q = 0,p in the absence of currents (j-0, i-0) 0) and (b) two of maxwell's equations contain curls. apply another curl-operator on both sides of the two equations. use the familiar mathematical identity curl (curl v) - grad(div v) - v2v why is the first term not important in our case? recall that the laplace operator is defined as v2 -+ +
