There are many problems with that hypothesis. First of all there is no
interaction between photons and a magnetic field. Secondly photons
present a pressure, not an attraction.

I have a better idea.

As the planet circles the sun, there is coupling of the iron core to the
sun's magnetic field. (Yes the iron core is not ferromagnetic due to the
heat being over the curie temperature, but there is still coupling due to
it being conductive and the associated electrical eddy currents).

Why is there any need for input of energy from an external source to
"keep planets rotating"?

Conservation of angular momentum does the job quite nicely....
