How does matter interact with matter?
An electron interacts with another electron or any other charged particle via its electric field/magnetic field.
A neutrino, a neutron, a photon does not interact with an electron via the electric force/magnetic force.
I think its already been mentioned, but photons absolutely do interact with electrons.
A photon is literally a quanta of electro-magnetic energy. While it does not interact with static electric or magnetic fields, it interacts with electrons by causing them to accelerate. If there is no scattering or absorption, this interaction instead delays the photon.
These interactions being the basis of lasers.
