Question

(1) What is meant by electromagnetic induction ? Name one device which works on the principle of
electromagnetic induction.
(i) Describe three different ways to produce induced current in a coil of wire.​

Answer 1

Electromagnetic induction

Electromagnetic induction is the production of voltage or electromotive force due to a change in the magnetic field. Electromagnetic induction was discovered by Michael Faraday in the 1830s. Many electrical components and types of equipment work based on the principle of electromagnetic induction.

Answer 2

Hey mate!!

here's your answer...

$\huge\sf\purpel{Electromagnetic\:induction}$

»Electromagnetic induction is the production of voltage or electromotive force due to a change in the magnetic field.

»Additional : -

»Electromagnetic induction was discovered by Michael Faraday in the 1830s.

Many electrical components and types of equipment work based on the principle of electromagnetic induction.

»Electric generators and Dynamos uses this.

»Ways to produce induce current in a coil :-

1. Moving a magnet towards a coil sets up a current in the coil circuit,
2. If a coil is moved rapidly between the two poles of a horse-shoe magnet, then an electric current is induced in the coil.
3. By taking two cunductiong coils and insert them over a non conducting cylindrical roll then on changing current flowing in one coil, an induced current is obtained in the other coil.
