Make coils of a different number of turns using insulated copper wire. Use magnets of different strengths to produce induced emf. Present this activity in the science club.

Thick insulated copper wires are used in the primary coil of a step up transformer and in the secondary of a step-down transformer. What is the necessity of doing this? Why is it so?

(a) Write down the name of parts numbered in the diagram.

(b) State the working principle of this device.

Michael Faraday, the father of electricity, did not even get elementary education. Are you not inspired by the achievements of Faraday in the field of science?

Conduct a seminar on “Contributions of Faraday and the hard work behind it.”

Energy is invaluable, especially electrical energy. Society must be convinced of the necessity of reducing the consumption of electrical energy. Prepare and propagate posters for this purpose.
