Which of the following is the correct relation between current density and magnetization?

موجودہ کثافت اور میگنیٹائزیشن کے مابین مندرجہ ذیل میں سے کون سا صحیح تعلق ہے؟

J = Grad(M)

J = Div(M)

J = Curl(M)

None of these

The correct relation between current density ( $mathbf{J}$ ) and magnetization ( $mathbf{M}$ ) is: $J = \nabla \times M$

This equation describes how the curl of magnetization produces bound current density in magnetized materials.
