Meanwhile, magnetic interactions between the spin and angular momentum magnetic moments of electrons also play a role in chemical reactivity such relationships are studied in spin chemistry. Electric forces also allow different atoms to combine into molecules, including the macromolecules such as proteins that form the basis of life. The electrostatic attraction between atomic nuclei and their electrons holds atoms together. The electromagnetic force is responsible for many of the chemical and physical phenomena observed in daily life. At high energy, the weak force and electromagnetic force are unified as a single electroweak force. These two effects combine to create electromagnetic fields in the vicinity of charged particles, which can accelerate other charged particles via the Lorentz force. Electromagnetic forces occur between any two charged particles, causing an attraction between particles with opposite charges and repulsion between particles with the same charge, while magnetism is an interaction that occurs exclusively between charged particles in relative motion. Electromagnetism can be thought of as a combination of electrostatics and magnetism, two distinct but closely intertwined phenomena. It is the dominant force in the interactions of atoms and molecules. The electromagnetic force is one of the four fundamental forces of nature. In physics, electromagnetism is an interaction that occurs between particles with electric charge via electromagnetic fields.
