# What is the principle of motor and generator?

Contents

The motor uses electricity. It works on the principle that when a current-carrying conductor is placed in a magnetic field, it experiences a force and rotates. The word ‘generator’ means to generate something, and an electrical generator produces (generates) electricity.

## What is the principle of motor?

An electric motor works on the principle that when a rectangular coil is placed in a magnetic field and a current is passed through it, a force acts on the coil which rotates it continuously. Hence, electrical energy is converted into mechanical energy.

## What is the principle of generator?

Electric generators work on the principle of electromagnetic induction. A conductor coil (a copper coil tightly wound onto a metal core) is rotated rapidly between the poles of a horseshoe type magnet. The conductor coil along with its core is known as an armature.

## What principle is followed in electric motor and electric generator?

An electric generator works on the principle of electromagnetic induction, that is, electric current is generated by a changing magnetic field.

## What is the difference between motor and generator?

The major difference between Motor and Generator is that a motor converts electrical energy into mechanical energy, whereas the generator does the exact opposite. The motor uses electricity whereas the generator produces electricity.

## What is the principle of electric generator Class 10?

The electric generator works on the principle of electromagnetic induction, in which when a straight conductor moves in a magnetic field, then the current is induced in the conductor.

## What is the principle operation of dc motor?

The DC motor is the motor which converts the direct current into the mechanical work. It works on the principle of Lorentz Law, which states that “the current carrying conductor placed in a magnetic and electric field experience a force”.

## What is the principle of DC generator?

A DC generator operates on the principle of Faraday’s laws of electromagnetic induction. According to Faraday’s law, whenever a conductor is placed in a fluctuating magnetic field (or when a conductor is moved in a magnetic field) an EMF is induced in the conductor.

## What is the principle of synchronous generator?

An alternator or synchronous generator works on the principle of electromagnetic induction, i.e., when the flux linking a conductor changes, an EMF is induced in the conductor. When the armature winding of alternator subjected to the rotating magnetic field, the voltage will be generated in the armature winding.

## What is the principle of electric motor Class 10 Brainly?

The principle of the electric motor is based on the fact that a current carrying conductor produces a magnetic field around it. A current carrying conductor placed perpendicular to magnetic field experiences a force. plz mark as brainliest.

## What is EMF and back EMF?

Counter-electromotive force (counter EMF, CEMF), also known as back electromotive force (back EMF), is the electromotive force (voltage) that opposes the change in current which induced it. CEMF is the EMF caused by magnetic induction (see Faraday’s law of induction, electromagnetic induction, Lenz’s law).

## How do motors and engines differ?

“People use both interchangeably, but the difference is that motors run on electricity and engines run on combustion. The engine converts various forms of fuels into mechanical force, while the motor transforms electrical energy into mechanical energy.”

## Are all motors generators?

All motors are generators. The emf in a generator increases its efficiency, but an emf in a motor contributes to energy waste and inefficiency in its performance. A back emf is a resistance to change in a magnetic field.
