Long thought to have no direct physical meaning, the Aharanov-Bohm effect showed that a nonzero value for this quantity could cause a phase shift even in a region where its curl was zero.
Long thought to have no direct physical meaning, the Aharanov-Bohm effect showed that a nonzero value for this quantity could cause a phase shift even in a region where its curl was zero. Its derivative is discontinuous across surfaces carrying surface current, and its very existence implies the nonexistence of magnetic monopoles, as the divergence of its curl is by definition zero. In the Coulomb gauge its divergence is set to 0, while in the Lorenz gauge its divergence is proportional to the negative partial derivative of the electric potential. For ten points, what is this quantity, whose curl is equal to the magnetic field?
