What is the reason for electromagnetic induction?

Electromagnetic induction is the generation of emf in one conductor due to rate of change of current in nearby conductor without any electrical connection. It works for very long distances. It is due to rate of change or flow of charges. Magnrtic fields due to moving charges are the reason.

What is the main principle of electromagnetic induction?

Faraday’s Principle of Electromagnetic Induction states that the emf induced in a loop due by a changing magnetic flux is equal to the rate of change of the magnetic flux threading the loop. The magnetic flux threading a coil of wire can be changed by moving a bar magnet in and out of the coil.

What is needed for electromagnetic induction?

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 magnetic field will be strongest inside the bar and at its ends (poles).

What is electromagnetic induction answer?

Electromagnetic Induction or Induction is a process in which a conductor is put in a particular position and magnetic field keeps varying or magnetic field is stationary and a conductor is moving. This produces a Voltage or EMF (Electromotive Force) across the electrical conductor.

What is electromagnetic induction class 12th?

The electromagnetic induction is a phenomenon in which an electric field or an electromotive force is induced or created in a conductor by the effect of a changing magnetic field in which the conductor is placed.

Which of the following is the fundamental significance of the Faraday’s discovery?

Faraday’s law describes how a changing magnetic flux induces an electric field. Faraday’s law is of special significance because it describes a coupling of the E-field and B-field and recognizes that this coupling requires a time variation of the flux. Only when ΦB changes is there an induced E-field.
