EM AND GRAVITY

This thread is about the relationship between electromagnetism and gravity.  (first, a small description of electromagnetism and gravity would be enjoyable.) second, how would one define that relationship?  does EM react to gravity, or gravity react to EM? or is it both?  would it theoretically be possible to use a for of "coil" to produce a gravitational force?  how would one go about doing that?  to be brief, any information about this would be very appreciated.

You are forgetting that light exists as both, a particle, and as a wave within the electromagnetic spectrum. As our physics guru >>2 pointed out, gravity can effect light. Thus, gravity is capable of interacting with electromagnetic forces, in a sense.

OP, if you are trying to unravel the mysteries of the universe without actually knowing anything about the subject, and artificially create gravity using... a coil, you are wasting your time.
