How to show Magnetic field Around magnet?

I have Created a dipole magnet in an unreal engine. I am not able to figure how can show magnetic field around the magnet on the dipole actor.

That would probably be a particle system, I can’t find any examples of magnetic field particles, I’m afraid.

It also could be a mesh added to the end of the magnet, which is the same shape, but with a translucent material applied, to make it look like a flux.
