If a wire is moved near a magnet what happens
Web14 nov. 2024 · Magnetism is the force exerted by magnets when they attract or repel each other. Magnetism is caused by the motion of electric charges. Every substance is made up of tiny units called atoms.Each atom has electrons, particles that carry electric charges.Spinning like tops, the electrons circle the nucleus, or core, of an atom.Their … WebIf a magnet is moving near to a wire it will generate an electric current and if an electric current is moving through a metal it can make a magnetic field. This is called an …

Web15 aug. 2024 · Description. This simple looking object was made by Michael Faraday in 1822. Its simplicity masks its true importance as the first surviving electric motor. In 1820 Hans Christian Ørsted announced his discovery that the flow of an electric current through a wire produced a magnetic field around the wire. WebIncreasing the strength of the magnetic field – If the same coil of wire is moved at the same speed through a stronger magnetic field, there will be more emf produced because there are more lines of force to cut.
