In this question we will learn about the basic concept of electrical bell, right? so in the given question we have to write some short notes on the electrical bell.
00:12
So the construction of the electrical bell is something similar to this.
00:16
So there will be an electromagnetic coil.
00:28
So there will be one electromagnetic coil and this would be connected with a battery, right? and there will be one screw, right? and one iron and there will be one iron strip which will be at the other end of the iron chip there will be one hammer right and there will be one dong so this is the basic construction of a electrical bell right so the concept is a soft iron strip with a hammer at the other end is kept close to the electromagnet and and when the current passes through the coil, this coil behaves like a magnet, right? and it will attract the iron strip, right? so due to this attraction force, this iron strip will move towards the coil and the hammer which is connected on the other end.

It will strike to the gong, right? it will strike to the gong, right? so with this, the sound is produced.
02:00
Right, when the iron strip is moving towards the gong, it will lose its contact with this screw and thus this circuit will be open circuit...
