Magnetic fields and gravitons ?

This might sound crazy , but could a magnetic field exchange gravitons with something
else , or can a magnetic field emit gravitons , And when a photon is emitted from the B field is the gravitational field from the B field transferred to the photon and then carried away by the photon .

someone has to have some input on this , Any input will be much appreciated.

Magnetic fields ARE photons.

I don't really know the answer to your question quantum mechanically, but classically, having a B field means there's an energy density u = |B|^2/2mu_0. An energy density contributes to the stress-energy tensor, and thus, by Einstein's equation, produces curvature. My naive intuition regarding the corresponding theory would tell me that yes, the field should be able to couple to gravitons.

I thought that photons were the excitation of the magnetic field.

Are you saying that magnetic fields can diffract .
