A magnetic field increases the rate of virtual photon production in a stationary frame because magnetism is a relativistic manifestation of charge as seen moving in the relativistic reference frame. A strong magnetic field will be produced by a large ensemble of charge carriers who will produce a large flux of virtual photons in the frame of reference in which the charges are moving. A magnetic field will be produced by the movement of electrons in the moving relativistic frame. This magnetic field will reach into a stationary frame of reference and impart into that frame the large flux of virtual photons generated in the frame of the relativistic moving charges.
The rate of virtual photon production will be the same in both the relativistic frame and the stationary frame to carry the effects of charge attraction between the two frames of reference. As an example, the soliton is the frame in which a large number of charges are moving. The quark zone inside the proton is where the three quarks orbit. This zone is the stationary frame of reference that is affected by the magnetic field produced by the soliton. The magnetic field will generate a large flux of virtual photons in the stationary frame of the quark zone inside the proton. It is the large infusion of virtual photons that catalyze the production of a virtual quark which is the beginning of the formation of a meson.
