Electro Magnet: An electromagnet is a type of magnet in which the magnetic field is produced by electric current. The magnetic field disappears when the current is turned off. This process of generating current in a conductor by placing the conductor in a changing magnetic field is called induction. Electromagnetic Induction: Electromagnetic induction is the production of a potential difference voltage across a conductor when it is exposed to a varying magnetic field. Electromagnetic induction is when an electromagnetic field causes molecules in another object to flow. Induction can produce electricity in coils , heat in ferrous metals , or waves in a radio transmitter. Finally it is refers to the phenomenon where an emf is induced when the magnetic flux linking a conductor changes. Magnetic Flux is defined as the product of the magnetic flux density and the area normal to the field through which the field is passing. It is a scalar quantity and its S. Electromagnetic induction or sometimes just induction 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 conductor. This process of electromagnetic induction, in turn, causes an electrical current - it is said to induce the current. Michael Faraday is generally credited with the discovery of induction in though it may have been anticipated by the work of Francesco Zantedeschi in

Invention: Michael Faraday is generally credited with the discovery of induction in though it may have been anticipated by the work of Francesco Zantedeschi in Around to , Joseph Henry made a similar discovery, but did not publish his findings until later Induced e. This effect was first observed and explained by Ampere and Faraday between and Faraday discovered that an e. Note that the e. For example, consider two coils as shown in Figure 1.

Coil A is connected to a galvanometer and coil B is connected to a battery and has direct current flowing through it. Coil A is within the magnetic field produced by B and an e.

This can be done by using the rheostat R, switching the current on or off, or c using an a. Representation: Electromagnetic induction is the production of a potential difference voltage across a conductor when it is exposed to a varying magnetic field. This growing and shrinking magnetic field can induce electrical current in another wire that is held close to the first wire. The current in the second wire will also be AC and in fact will look very similar to the current flowing in the first wire.

It is common to wrap the wire into a coil to concentrate the strength of the magnetic field at the ends of the coil.

Wrapping the coil around an iron bar will further concentrate the magnetic field in the iron bar. The magnetic field will be strongest inside the bar and at its ends poles.

Lenz's Law: When an emf is generated by a change in magnetic flux according to Faraday's Law, the polarity of the induced emf is such that it produces a current whose magnetic field opposes the change which produces it. The induced magnetic field inside any loop of wire always acts to keep the magnetic flux in the loop constant.

In the examples below, if the B field is increasing, the induced field acts in opposition to it. If it is decreasing, the induced field acts in the direction of the applied field to try to keep it constant.

Applications of electromagnetic 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. If the wire is connected through an electrical load, current will flow, and thus electrical energy is generated, converting the mechanical energy of motion to electrical energy Electrical transformer The EMF predicted by Faraday's law is also responsible for electrical transformers.

When the electric current in a loop of wire changes, the changing current creates a changing magnetic field. If the two ends of this loop are connected through an electrical load, current will flow.

Magnetic flow meter: Faraday's law is used for measuring the flow of electrically conductive liquids and slurries. Such instruments are called magnetic flow meters.
