Which fundamental force explains why oppositely charged particles attract?
PhysicsElectromagnetism
Quick Answer
The electromagnetic force explains attraction between opposite charges. It is the force behind electric and chemical interactions.
The Full Story
Opposite electric charges attract because they interact through the electromagnetic force. This same force also causes like charges to repel and governs the behavior of electrons around nuclei. It is the reason atoms, molecules, and all chemistry are possible. Classical electromagnetism was unified by Maxwell in the 19th century, and quantum electrodynamics later described its particle nature. Nearly everything in everyday life, from friction to chemistry, depends on electromagnetic interactions.
