I would like to thank my principal Dr. 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. Working and Construction: Current is produced in a conductor when it is moved through a magnetic field because the magnetic lines of force are applying a force on the free electrons in the conductor and causing them to move.

This process of generating current in a conductor by placing the conductor in a changing magnetic field is called induction.

This is called induction because there is no physical connection between the conductor and the magnet. The current is said to be induced in the conductor by the magnetic field. One requirement for this electromagnetic induction to take place is that the conductor, which is often a piece of wire, must be perpendicular to the magnetic lines of force in order to produce the maximum force on the free electrons.

The direction that the induced current flows is determined by the direction of the lines of force and by the direction the wire is moving in the field. In the animation above the ammeter the instrument used to measure current indicates when there is current in the conductor. If an AC current is fed through a piece of wire, the electromagnetic field that is produced is constantly growing and shrinking due to the constantly changing current in the wire.

This growing and shrinking magnetic field can induce electrical current in another wire that is held close to the first wire. The magnetic field will be strongest inside the bar and at its ends poles. It is common to wrap the wire into a coil to concentrate the strength of the magnetic field at the ends of the coil.

If an AC current is fed through a piece of wire. Wrapping the coil around an iron bar will further concentrate the magnetic field in the iron bar. This growing and shrinking magnetic field can induce electrical current in another wire that is held close to the first wire. Lenz's Law: When an emf is generated by a change in magnetic flux according to Faraday's Law. In the examples below. If it is decreasing.

The induced magnetic field inside any loop of wire always acts to keep the magnetic flux in the loop constant. When a permanent magnet is moved relative to a conductor. Applications of electromagnetic Induction Electrical Generator: 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. If the wire is connected through an electrical load.

Electrical transformer The EMF predicted by Faraday's law is also responsible for electrical transformers.

Magnetite Separation Production Line

When the electric current in a loop of wire changes. If the two ends of this loop are connected through an electrical load. A second wire in reach of this magnetic field will experience this change in magnetic field as a change in its coupled magnetic flux.

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. This concept has many far-reaching ramifications that touch our lives in many ways: Although its mathematical representations are cryptic. The principles of electromagnetic induction applied in many devices and systems.
