Simple electric bell that works with 4v to 9V battery source, works well with 4 x D cell holder.
When electricity is supplied, the electro-magnet E gets magnetised and attract the clapper (A), causing it to strike the gong. This breaks the circuit the contact point T and thus electromagnet E demagnetise and the clapper returns back to its original position. At this point, the circuit is closed again and the process repeats.
