Understand the Magnetic vector-potential equation relationship used by Magnetics.

Where to find it

Magnetics → equations

How to use it

Compare the terms, signs and units with your intended physical assumptions before choosing model inputs.

Result

Equation: -\nabla\cdot\left(\nu\nabla A_z\right)=J_z.

Troubleshooting

The equation describes the model assumptions; it is not a separate editable boundary condition. Check the parent physics page for setup and limitations.
