Electromagnetic or magnetic induction is the production of an electromotive force (emf) across an electrical conductor in a changing magnetic field. Michael Faraday is generally credited with the discovery of induction in 1831, and James Clerk Maxwell mathematically described it as Faraday's law of induction.
The emf generated by Faraday's law of induction due to relative movement of a circuit and a magnetic field is the phenomenon underlying electrical generators. When a permanent magnet is moved relative to a conductor, or vice versa, an electromotive force is created.
Now the magnetic field will exert a force on the current in the rod. The force on the rod will be a I ×B I × B; that is aIB a I B acting to the left. In order to keep the rod moving steadily at speed v v to the right against this force, work will have to be done at a rate aIBv a I B v.
The electric fields caused by those forces are E n (non-Coulomb, non conservative). 2. Faraday’s Law - The induced emf in a closed loop equals the negative of the time rate of change of the magnetic flux through the loop.
The change in the magnetic flux linking the coils of the solenoid results in an induced emf in the circuit. Faraday’s law states that the magnitude of the induced emf is proportional to the rate at which the magnetic flux linkage changes. This emf drives an induced current through the closed circuit.
An induced emf occurs when there is a changing magnetic flux through a stationary conductor. - The force that makes the charges move around the loop is not a magnetic force. There is an induced electric field in the conductor caused by a changing magnetic flux.
