It is rumored that spinning a magnetic field at high speed can create gravitational effects I don't know if it's true or not can anyone clerify why this is a rumor?

some say that spinning a superconductor also produces gravitational effects but why?  I know how it is thought to be done but I can't seem to find any theories as to why doing stuff like this should effect gravity at all. Plus there is a lot of conspiracy theories surrounding anything regarding gravitational effects and it's  made it hard to look into the subject without running into a bunch of conspiracy nonsense, can anybody help find out why spinning things like magnets or superconductors effect gravity?

If you spin a magnet it generates electromagnetic radiation this radiation carries energy which has mass the source of gravity.
The effect is rather small!

On the macro scale this idea has merit.  It is accepted that both the gravitation force and electromagnetic force of attraction or repulsion are ratio-ed to matter bulk and subject to inverse square law reduction

When you say "electromagnetic energy with mass" I assume you are referring to the electromagnetic spectrum. like radio, micro, infrared and light waves.  I thought light had no mass, But E=mc² does say that mass is made of energy and light is energy so I guess it could have a super small amount of mass.

And there is that idea that gravitons travel with light at light speed so it could be possible.

I find it ineresting that the spinning superconductor experiments were able to slightly improve the generation of gravity by hitting the spinning YBCO disk with the proper resonance electromagnetic waves.  Perhaps it is of great significances to increasing the yield of gravity mods in the experiment.

Also light is inherently a wave yet it carries gravity without being a particle.  I wonder if the cooper pairs in the superconductor disk might be able to emit gravity waves/gravitons via thier BEC like properties as waves/phonons. hmmm.. could be possible. []

SS, I was not thinking about light which travels through a magnetised space but the background dark electromagnetic force that is pushing the stars apart with a magnoflux force 23 times more powerfully than gravity is attracting them together.

I thought light had no mass, ...

What you're thinking of is the notion that light has zero proper mass (aka rest mass). It has mass in the sense of inertial mass, aka relativistic mass.

But E=mc² does say that mass is made of energy...

That is not what E=mc² says. It says that anything that has mass also has energy in accordance to that relationship. But it doesn't mean that mass is made of energy.

In any case the answer to your question is no. First off there's no such thing as a spinning magnetic field. Such a notion is meaningless. And if you're thinking of a spinning magnet than it doesn't produce a gravitational field (at least not something that is large enough to be measured with modern instruments if the magnet is laboratory size) and neither does a rotating superconductor reduce a gravitational field.
