Hello, I am having to find the rotational diffusion of a magnetic particle inside of water. I already have a diffusion coefficient but I do not know how to take into account the restoring force that the particle will feel from the magnetic field.
The info that I know is: BField Strength mmagnetic moment Drotational diffusion coeffiecent I have been using the online program Hydra++ to get the rotational diffusion coeffiencent. Does anyone know how to take into account the restoring force of the magnetic field? Thank you.

The particle will experience torque (moment of force)
$$ \boldsymbol{\tau} = \mathbf m \times \mathbf B $$
