WebIn the macroscopic Ampere law here, the net electric current includes both the bound current Jb(r) due to magnetization as well as the free macroscopic current Jf(r) due to electric conductance. Altogether, this gives us ∇× B = µ0Jb + µ0Jf = µ0∇× M + µ0Jf, (29) which we may rewrite as ∇ ×(B− µ0M) = µ0Jf. (30) Webn. 1. a. The process of making a substance temporarily or permanently magnetic, as by insertion in a magnetic field. b. The extent to which an object is magnetized. 2. The property of being magnetic.

WebOct 1, 2024 · The bound surface current that matters to us is the one along the cylindrical side of this object. This cylindrical surface is located at r = R and the bound surface current density is given by, All of the current is flowing along the z axis. Neglecting the edge effects means we may ignore the r axis directed currents at the edge faces. There are two important issues regarding the circuital law that require closer scrutiny. First, there is an issue regarding the continuity equation for electrical charge.
