Magnet & Electricity

When electric current flows through a conductor, a magnetic field is created around the conductor. This phenomenon is called magnetic effect of electric current. The relative strength and direction of magnetic field due to a conductor depends on the direction of electric current and shape of the current carrying conductor. When a magnet is placed in an electric field, it experiences some force. Similarly, when a current carrying conductor is placed in a magnetic field, it experiences some force. The interaction of these forces results in various phenomena. Many electrical gadgets work on some or other of these phenomena. Electric motor and electric generator are key devices which work on electromagnetism.
