When we study the topics of electromagnetism we come across one of the important lodge that is called Faraday's laws which basically describes the key point leading to the practical generation of electricity or electromagnetic induction.
the law was proposed in the year 1831 by the experimental physicist and chemist named Michael Faraday.
so you can see why the name of the lord is come from that being said the blood is low or the laws of electromagnetic induction is always equal in the result of the observation of the experimental at that point of time .
He performed three main experiment to discover the phenomenon of electromagnetic induction.
Relationship between the induced EMF or flux.
in the first experiment he proved that when the strength of the magnetic field is embedded in a leader induced current is produced an ammeter is connected to the law of the wire animated deflected when the magnetic was move toward the wire.
In the second experiment he proved that passing a current through an iron rod would make it electromagnetic.
he observed that when there is a relative motion exist between the magnet and the coil The induced electromotive force is created.
when the magnet was rotated about its Axis no electromagnetic force was observed cut off when the magnet was rotated about its own axis then the induced electromotive force was produced.
Does there was no deflection in the emitted when the magnet was held stationary.
while conducting the third experiment he recorded that the Galvanometer did not so any deflection and no induced current was produced in the coil when the coil was moved in a station a magnetic field. bimetal deflected in the opposite direction when the magnet was moved away from the loop.
The positions of magnet
Magnet at rest
No deflection in the galvanometer
Magnet moves towards the coil
Deflection in the Galvanometer in one direction
Magnet is held stationary at the same position
No deflection galvanometer
Magnet moves away from the coil
Deflection in the Galvanometer but the opposite direction.
Magnet held stationary at the same position
No deflection in galvanometer.
conclusion after conducting all experiment Heritage finally concluded that if the relative motion suggested between a conductor in a magnetic field attracts linkage with a coil change this and these changes in the class produced voltage across the coil.
Ramesh lodge basically states of when the magnetic flask for the magnetic field changes with the time the electromotive force is produced additional Michael Faraday also permitted to launch on the basis of above experiment.
Faraday's first law
what is first law of electromagnetic induction system that the whenever a conductor is placed in the varying magnetic field the electromagnetic field produced induced electromotive force.
if the conductor circuit is closed a current is also induced which are called induced current
A way of charging magnetic field
By rotating the coil related to the magnet.
By moving the coil in 2 or out of the magnetic field.
By changing the area of a coin placed in the magnetic field.
