ABSTRACT
Motors function by exploiting electromagnetic force, one of the four fundamental forces of nature. As might be obvious from the name, electromagnetism defines a relationship between magnetism and electricity. In fact, magnetic and electric forces are really fundamentally the same sort of thing; both are defined by the exchange of photons between charged particles, called an exchange force. The current will induce a magnetic field around the wire. Placing that wire loop between two poles of a magnet would cause the magnetic field induced by the current and the magnetic field of the magnets to interact. The basic principle is straightforward. Remember that a current induces a magnetic field, and as a magnetic field cuts across a conductor, it in turn induces a current. The strength of the magnetic field is not shared among the conductive loops; the force is multiplied. The more the conductor is exposed to the magnetic field, the stronger the effect.
