Answer 1

hey|!!!.

here is u r answer.
_________________________________________________***

➡️➡️⬇️

**
a motor is a device which convert electrical energy to mechanical energy.

***
uses :---

they are used in fans , Washing machine, refrigerator,mixer and grinder.

*****
principal of motor:----

a motor works on the principal that when a rectangular coil is placed in a magnetic fields and current is passed through it ,a force on the coil which rotates it's countinously.
*****
:------

construction of a motor.

a device which reverse the direction of current through a circuit is called a commutator .

-----**

the function of commutator rings is to reverse the direction of current flowing through the coil every time the coil just passes the vertical posting during revolution.

Answer 2

Hello Madam✌️

Answer Of Your Question☺️

→Electric Motors Work On The Principles Of Electromagnetism.A Electrical Motor Is A Machine Which Can Convert Electrical Energy To Mechanical Energy.

Firstly The Device(Motor) Turns The Energy In Motion By Usually Rotation.Device Contain With A Coil Of Wire Which Can Create A Magnetic Field.
After That,A Electric Is Sent Through A Loop Of Wire Positioned Inside The Magnetic Field By The Coil Of Wire.
It Turns Out When An Electric Flows Through A Magnetic Field, The Charges Feel A Magnetic Force On Them At 90° To The Direction They Are Moving.

In The Diagram,There Are A Loop Of Wire Inside The Magnetic Field, Both Side B and D Flowing Current Opposite Side. Because, The Magnetic Forces They Feel Also Go in Opposite Directions. Side B Feels A Force Inside , And side D Feels A Force Outside. Those Forces Together Cause The Loop Of Wire To Rotate.
