Electromagnetic induction also known as faradays law of electromagnetic induction or just induction but not to be confused with inductive reasoning is a process where a conductor placed in a changing magnetic field or a conductor moving through a stationary magnetic field causes the production of a voltage across the. Within two months faraday found several other manifestations of electromagnetic induction.

The eddy current flows in a closed loop and acts like the current in a coil or solenoid that produces its own magnetic field.
Electromagnetic induction with example. However since the charges are not bounded by a narrow conductor the currents flow in circles called eddy currents. Electromagnetic induction was discovered by michael faraday in 1831 and james clerk maxwell mathematically described it as faradays law of induction. Electromagnetic induction is a current produced because of voltage production electromotive force due to a changing magnetic field.
Faradays law of induction and lenzs law faradays law of induction uses the fb magnetic flux throughout an area of space surrounded by a wire loop. A good example of this is the way power is generated such as at a hydro electric power plant. When a changing magnetic field is somehow applied to such a conductor electromagnetic induction occurs.
The applications of electromagnetic induction include electrical components like transformers inductors as well as devices like generators and motors. Electromagnetic induction occurs when a circuit with an alternating current flowing through it generates current in another circuit simply by being placed nearby. For example he saw transient currents when he quickly slid a bar magnet in and out of a coil of wires and he generated a steady dc current by rotating a copper disk near the bar magnet with a sliding electrical lead faradays disk.
Electromagnetic induction name institution abstract electromagnetic induction is a principle which predicts the behaviour of the electric currents whenever they interact our website is a unique platform where students can share their papers in a matter of giving an example of the work to be done. Electromagnetic induction if the wire is then wound into a coil the magnetic field is greatly intensified producing a static magnetic field around itself forming the shape of a bar magnet giving a distinct north and south pole. This relationship allows them to affect each other without contact as in the maglev train example or through electromagnetic induction.
What is electromagnetic induction. Rather than using a spinning coil in a constant magnetic field another way to utilize electromagnetic induction is to keep the coil stationary and to spin permanent magnets providing the magnetic field and flux around the coil. An alternating current is the kind of electricity flowing through power lines and home wiring as opposed to a direct current which we get from batteries.
