Distinguish between electromagnetic induction and Electromagnetism

Expert Solution

Solution : Electromagnetic induction is the process of inducing current in a metal without the use of battery . But definitely we have to use some source of emf to have current. Because current is present due to emf or potential difference.Potential difference would allow the current to flow in the circuit from high potential to low potential .

Take a circular loop and move a magnet in and out rapidly we will see that as long as we continue to do this current will be induced and this can be checked by connecting bulb in series with it.And this is accordance Faraday's law of Induction.

PRINCIPLE: By changing the magnetic field continuously through a conductor with time produces a Potential drop .

Moreover as fast as we move the magnet or faster we change the magnetic field more will be the magnitude of Current induced.

And electromagnetism is producing a magnet with the help of electricity.Consider a Solenoid carrying current ,it will produce magnetic field along it's axis though being non uniform .And now if we place an iron rod in its core then it will get magnetized .This is called electromagnetism .

Electromagnetic Induction

We are rotating a 2 m long metallic rod with an angular frequency of 200 rad/s with an axis normal to the rod passing through its one end. And on to the other end of the rod, it is connected with a circular metallic ring. There exist a uniform magnetic field of 1.5 T which is parallel to the axis everywhere. Find out the emf induced between the centre and the ring?

1. Faraday’s law of electromagnetic induction is a law that states that when the magnetic flux linking a circuit changes, an electromotive force is induced in the circuit proportional to the rate of change of the flux linkage. Please click the link: https://phet.colorado.edu/sims/html/faradays-law/latest/faradays-law_en.html And observe the fluctuation of induced current in the circuit by moving the magnet.
