Question

Name the two devices which work on the principle of electromagnetic induction

Answer 1

The electric generators and dynamos uses rotating magnets to induce an electric current in conducting wire coils surrounding the generator's armature. We have a few videos on "Magnetic Effects of Electric Current" of Class X Science.

Answer 2

2 devices based on ELECTROMAGNETIC INDUCTION are:

• Generators & Motors
• Doorbells & Buzzers

Electromagnetic induction refers to an induced EMF and resultant current flowing through a circuit due to instàntaneous change in the magnetic flux through a particular area vector.

For example :

• In generators, a conductor coil is rotated in between the poles of a magnet such that the magnetic flux changes rapidly and produces current. Presence of current is confirmed by deflection in galvanometer.
