Dorebell
1. Working principle of a doorbell
Now a days every house is having a facility of
doorbell . Doorbell makes our life easier. It is a single
push of a button by which anyone who came to our
house can present their request to us and enter into
our home .Compared to modern technology ,a
doorbell may seem a bit boring.
Doorbell is a little device that put the
scientificprincipleof electromagnetism into action in
a useful way. The heart of a doorbell is an electro
magnet. Electromagnets are coils of wire wrapped
around a small piece of magnetic metal. Firstly, when
2. you press a door bell button it completes an electric
circuit that allows the electricity to flow through the
door bell and next the electricity passes through the
wire which creates a magnetic fieldaround the wire
and then the magnetic field is generated by the
electromagnet which is used to power a mechanism
that creates a door bell sound.
Secondly, the main part of a doorbell
mechanism is the transformer which converts the
household voltage to lower voltage .The simple
doorbell uses the magnetic field mechanism which is
created by the electromagnet to move a magnetic
piston to strike the tone bars ,after that it produces a
ding dong sound that is probably heard many times in
our house.
