Radiation gravitates - anything that carries energy, momentum and stresses is a source of a gravitational field, i.e. a curvature in the fabric of space:

An electromagnetic field have its own gravitational field, because an electromagnetic field contains energy, momentum (Maxwell's stress-energy tensor), and so on, it is considered as a real thing capable of gravitating, as such, it will produce a gravitational field of its own. This gravitational field is in addition to that produced by the matter of the charge or magnet. Electric charges and magnets are manifestations of certain types of matter, most particularly electrons. 

Since matter carries energy (via E=mc^2), such objects will have a gravitational field and so they will curve the fabric of space. So, one way in which a charge or a magnet will curve the fabric of space is by virtue of its matter.

Please confirm the above.

Where is the space expanding faster than the speed of light?

The answer to the question is that, the limitation in the speed of light is applicable within a gravitationally bound system - definitely within a galaxy (up to the zero-gravity sphere around it, or within clusters or super cluster or mega clusters of galaxies respectively,

Only the space beyond that is dominated by Dark Energy that expands the space. Generally, intergalactic space expands but not within a galaxy.

However, space is not expanding faster than light everywhere; only after certain distance towards the edge of the universe space can expand faster than light, the space before that in slower than the speed of light.

When you are seeing a distant galaxy, you are actually seeing its light year travelled distance but at the time of your observation that galaxy might have changed its location to a new location known as its proper distance.

So a general understanding is that when the galaxy's proper distance is greater than the light year travelled distance then only the galaxy is considered to be receding faster than light speed, not before that.
