and how does this interaction affect the speed of light?

A changing magnetic field will create a changing electric field and a changing electric fiied will generate a changing magnetic field. That's how waves propagate. The speed of light is determined by two physical constants in the universe. One of them is permeability and is associated with the magnetic field; the other is permittivity which is associated with the electric field. The speed of light is 1 divided by the square root of the two multiplied together.

One generates the other (Maxwell equations). Moving electric charge generates magnetic field (Ampère's law) and a changing flux of magnetic field generates an electric field (Faraday's law). This however does not determine the speed of light which is a constant related to permittivity and permeability of the vacuum (free space) or the material through which light is transmitted.

Magnetic fields and electronic is the same and do not affect the speed of light. The speed of light is used for radio wave lengths calculations.
