How do magnetic fields curve spacetime?

448 views

According to the Einstein field equations, matter and energy both curve spacetime. I'm wondering how magnetic fields contribute to the curvature of spacetime. I have a few questions:

1. If there is a magnetic dipole sitting in space, how strong would it need to be to create stable orbits for some object nearby?

2. Do there exist any naturally occurring magnetic fields in the universe strong enough to cause something to orbit it?

3. Can humans generate magnetic fields strong enough to cause observable gravitational effects, ie an artificial gravity field?

4. Does there exist a nice solution for the metric due to a magnetic dipole, or maybe a general potential field?
