Question

Does all matter have a magnetic field. If so, does it have it's own small gravitational pull?

Answer 1

First, gravity and magnetism are two different things, at least as far as physics has gotten to date. And mass always has gravity, however small the mass is. But gravity is a very weak force, so it takes a lot of matter to begin to have a meaureable effect.

Magnetism is more complicated. If, by 'matter', you mean atoms and molecules, then yes, all matter has a magnetic field, except it is random in direction and so you cannot detect it. I mean, it all cancels/averages out, excepting in those few metals that do manage to align these magnetic forces into what we know as magnets.

If you are asking electrons and protons and neutrons, well, neutrons do not, and protons and electrons, at least moving ones  - and quantum mechanics says they are always moving - do. If you are asking about matter per se,  then it is difficult to say. The interactions of the very smallest particles are not so easy to disect and describe.

Answer 2

No, most matter is not magnetic.  Gravity and magnetism are separate forces, and don't rely on each other - everything with mass has gravity, but that doesn't make it necessarily magnetic.

Answer 3

No.  The gravitational field is a property of matter.  The magnetic field is an artifact only of a changing electric field.  Most materials are not magnetic in any sense (ferromagnetic, diamagnetic, paramagnetic etc).  So far, science has found no connection between gravity and any of the other known forces.
