Basic working principle of simple buzzer is electromagnetism.
Material required:
Copper wire (insulated and bare Ended), insulated wire for connection, low-voltage
Power supply or Battery, Hacksaw blade or metal strip, nail or screw
Description: Wind the copper wire around
the nail or screw (about 150 – 200 turns) fixed on base. This will form an
electromagnet. Fix the Hacksaw blade or metal strip on base in such a that the other
end of the blade will remain 2-3 mm above the nail or screw. Connect one end
of electromagnet wire with battery. Connect the other terminal of battery with
fixed end of blade. Another end of electromagnet wire is connected in such a way that it touches the top of the
blade. In this way buzzer sound is produced.
