HOW TO WORK BEL?
The diagram below shows the circuit in an electric bell. If the bell is pressed into a magnet electric iron and a hammer so that pulling the hammer hitting the bell. However, if the circuit is disconnected, the iron loss of magnetic power and bat pulled back again. Once the bats have returned a complete range / whole again and the process repeats.
QUESTION:
Can you think of other tools that use electric magnets to generate a sound? Telephone use electric magnets to make a thin disc which is called the diaphragm can vibrate.
