= Bound current
{title2=$\mathbf J_b=\partial_t\mathbf P+\nabla\times\mathbf M$}

The current associated with <electric polarization> and <magnetization> in matter. If the magnetic response is neglected, it is $\mathbf J_b=\partial_t\mathbf P$. It is distinguished from a free conduction current in the <Maxwell equations in matter>.
