There's something (not confirmed) called the Hawking-Unruh Effect. It's similar to Hawking radiation, but instead of a black hole, this effect involves an accelerating observer.

It's a strange sort of thing, since an observer at rest wouldn't see the black-body radiation, but the accelerating observer would.

One note: Neutron only have a magnetic field because they are made of electrically charged quarks. Fundamental particles with no electric charge also have no magnetic dipole.
