SUMMARY
The discussion centers on the phenomenon of total bound current in a cylindrical magnetization scenario, specifically with a permanent magnetization vector \(\vec{M}=(ks)\hat{z}\), where \(k\) is a constant and \(s\) represents the cylindrical coordinate. It is established that when the magnetization is confined within a cylindrical shell of inner radius \(a\) and outer radius \(b\), the total bound current can indeed be non-zero. The presence of a surface current circling the cylinder is confirmed when the magnetization aligns with the cylinder's long axis.
