Michael Faraday and James Clerk Maxwell demonstrated that electric and magnetic forces have been unified through a principle of electromagnetism. Within the twentieth century, the development of quantum mechanics led to a trendy understanding that the primary three basic forces (all besides gravity) are manifestations of matter (fermions) interacting by exchanging virtual particles known as gauge bosons. This Customary Mannequin of particle physics assumes a similarity between the forces and led scientists to foretell the unification of the weak and electromagnetic forces in electroweak principle, which was subsequently confirmed by remark. Newton’s legislation of gravitation is an example of action
