WebMar 17, 2024 · In essence, it would imply that we could "connect" the bound (polarization) currents of moving magnets into our circuit, so as long as displacement currents "diverge" and "converge" at both our magnet and our circuit to ensure the continuity of current. WebPhysically, the bound currents on the surface of a magnetized material (and also in its volume for a non-uniform M) originate from the mis-cancellation of the microscopic …

It is a vector field whose magnitude is equal to the local value of the magnetic moment per unit volume. …
WebWhen you put a substance in a magnetic field, the substance gets magnetized and a bound current is produced. The bound current itself then produces a magnetic field, so there …
WebCurrent passes unless we apply an external electric field to metallic conductors. These free electrons inside the conductor are free charge, whereas in the case of dielectrics there … WebMay 5, 2011 · Because .P=bound charge (sorry, having trouble with the math text), if you take the time derivitive of each side, by comparison to the continuity equation, you see that the time derivitive of polarization "acts like" a current. But we know that a static electric field only causes a static polarization.
