What exactly do you mean by surface particle? Is the dimer constructed with a raspberry? It is usually enough to just assign a dipole to a particle with the “dip” or “dipm” parameter at particle creation, then it will have an interaction with the magnetic field. It is also worth considering not to put the dipoles on the surface particles, but only on the central particles of your dimers, if your model allows for that.
I have created a dimer. How can I apply a magnetic field on the surface particle?
I have used tutorial ferrofluid Part2, but it is not working. It is working only for central particle.
