Magnetic Force Report¶
The force is calculated using the Maxwell stress tensor \(\mathbb{T}\) [Pa] given by
\[
\mathbb{T} = \mathbf{B} \otimes \mathbf{H} - \frac{1}{2} \left(
\mathbf{B} \cdot \mathbf{H}
\right) \mathbb{I}\, .
\]
The force \(\mathbf{F}\) [N] is then given by integrating over the surface \(S\) of the center pole body with
\[
\mathbf{F} = \int_S \mathbb{T} \cdot \mathbf{n} \, dS,
\]
where \(\mathbf{n}\) is the normal along the surface.
