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:
B-Field Strength
m-magnetic moment
D-rotational 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
