ELECTRIC BELL
ELECTRIC BELL
- When the iron strip is in contact with screw,the current flows through the coil which becomes an electromagnet
- It the pulls the iron strip.In the process,the hammer strikes the gong of the bell to produce a sound when the electromagnet pulls the iron strip.The circuit breaks. the coil is no longer electromagnet it no longer attracts the iron strip the iron strip comes backs to its orignal position and touches the contact screw again this again complete the circuit and the coil again again attracts the iron strip and strikes the gong this process is repeated in quick session the hammer strikes the gong everytime the circuit is complete this is how the bell rings.
i hope its a help to u
