ELECTROMAGNETIC INDUCTION.

After the Danish scientist, Orstd demonstrated the ability of the electric current to generate an electromagnetic field around it.
Galvanometer.

Scientists have begun to question the use of the magnetic field to generate an electric current. There have been some attempts, but most importantly, the world experience of Michael Faraday in the 1930s. It was necessary to use a means to detect the current, the Galvanometer was the first device used for this purpose. It consists of a flat vertical coil with many folds and a compass inside it. When a current passes through the coil, a magnetic field is generated that affects the direction of the compass needle. In one of the Faraday experiments, a large coil with many galvanized ligaments arrived at the Galvanometer.
Electromagnetic Induction.

When a magnet rod is passed inside the coil, the needle moves slightly and then returns to its place when the magnetic rod is removed from the coil, thereby making sure that the electric current is generated in the coil. This phenomenon has been called "electromagnetic induction".

It was a discovery of the most important and until that date, electric currents were generated only from batteries. If Faraday's discovery opens up new horizons to convert kinetic or mechanical energy into electric energy, for example, if we move a magnetic rod continuously inside and outside the coil, a current flows in a circular direction, The opposite again means that it generates an alternating current and using an engine to move the magnet is obtained by an electric generator.

Changing the magnetic field when moving the magnet is what drives the voltage so that the same effect can be obtained if we move the wire or coil through a magnetic field. In both cases, the connector cuts the power lines or magnetic field lines.Faraday also conducted experiments on the inverse of electromagnetic induction. He observed that if a wire is placed in a magnetic field and a current is ordered, the wire moves. This means that the force is driven by the current and magnetic field. Thus, if a wire moves in a magnetic field in which a current is generated, this principle is used to generate electricity. If a wire is placed in a magnetic field, it generates the force of the wire and this principle is used to make the electric motors.



James Clark Maxwell.a Scottish scientist in physics and calculus, he contributed a metathetical theory that presented the light as electromagnetic waves.



The current here passes from the fewer windings column to the exponential parallel windings column which will increase the alternating current voltage as per windings amount.


Electromagnetic induction generates when a conductor moves within a magnetic field. The inverse phenomena are harnessed to make the electric motors because passing an electric current in a conductor inside a magnetic field will force the conductor to rotate.


These huge transformers are used in the electric power stations in this type of transformers, the windings are wrapped on the steel column more or less than the other parallel column which will result by raising the power factor or decreasing the power factor.
