What are electromagnetic proceses?

i'm a bit confused - what are electromagnetic proceses? are compton scattering, coulomb scattering and pairproduction examples of electromagnetic processes?

thanks

Electromagnetic processes are processes that occur due to the electromagnetic interactions of the particles involved. So yes, Compton scattering and Coulomb scattering are electromagnetic processes. Pair production can occur due to the electromagnetic interaction, but at very high energies it can also proceed via the weak interaction. Basically, if you can write down a Feynman diagram that has a photon in it somewhere, the electromagnetic interaction is involved.
