How can neutron stars have a magnetic field?

Question

I've read that the neutron stars have incredibly strong magnetic fields due to their intense density, temperature, and rotation speed. But how can something completely made up of neutrons, which have a neutral charge, radiate anything even resembling magnetism?

Answer 1

Yes.  Neutron stars have a very strong magnetic field.

Answer 2

Good question.  Neutron stars are not completely made up of neutrons---they have a crust of reglar matter, mostly iron, a couple meters thick.  Even the neutron material is impure and somewhat conductive and can support a magnetic field.

Answer 4

Neutrons are made up of quarks, which carry electric charge.  The internal motion of the quarks, and their spin, generate  a magnetic field.
