Write applications of magnetic field of a current carrying solenoid.
Answers
Answer:
Name some devices in which electric motors are used. Appliances like electric fans, washing machines, mixers, grinder, blenders, computers, MP3 players, etc. uses electric motors.
Answer:
It is used to magnetic metals which are non -magnetic.
The magnetization works on the alignment of electrons in a straight manner.
Basically in non-magnetic metals, electrons are gathered here and there.
This above diagram is of a metal bar in which the electrons are gathered here and there.
So to magnetize that metal, solenoid is used.
Solenoid align the electrons in a magnetic field manner.
So, coming to your question
Solenoid applications
1>>>>>Old Doorbells
(So, how they are using solenoid in doorbell)
(When the button gets pushed (Your doorbell) ,then it gives a voltage to the wire which is wound on a non-magnetic material ,then the non-magnetic material gets magnetize and it hits the metal .
So you will be thinking that it's hitting one time.
No, it's not like that.
A small voltage regulator is used, which is used to vary the current and as the current varies, it is hitting that metal (10-30) times, but it depends upon the voltage and how accurately that voltage regulator is designed on a PCB, which is inside the Doorbell)
