Explain briefly about electromagnetic induction? |
|
Answer» Electromagnetic InductionThis process by which a changing magnetic filed in conductor induces a current in another conductor is called electromagnetic induction. The scientist Michael Faraday did many experiments in this field.The phenomenon of electromagnetic induction is the existence of an induced current in a circuit (such as a coil) placed in a region where the magnetic field motion changes with the time. The magnetic field may change due to relative motion between coil and magnet placed near the coil . We know that a current-carrying conductor also produces magnetic field that changes with a change in the current flowing through it. Thus if a coil is placed near to a current-carring conductor, an induced current in the coil may setup due to a change in the current through the current-carrying conductor. Hi, electromagnetic induction means the phenomenon of generation of an electric current in a circuit from magnetic effects i.e.,by changing the magnetic flux linked with it is called electromagnetic induction. |
