Whats an electric bell, how does it work, and whats its uses?
There are Various ways that can make an Electric bell but they work on the same principle.With tubular door bell,when the bell push is operated an electric current is past through a coil of wire wound on a hollow iron core in the core there is a spring loaded iron bar that is able to move in the hollow core the current produces a magnetic Field that pulls the spring loaded bar through the core which strikes one of the tubes when the bell push is released the spring returns the floating bar back to hit the other tube.
