# Your question: What is electromagnetic induction explain it with suitable example?

Contents

When a conducter moves through a magnetic field, a voltage is produced across the conducter this is called electromagnetic induction. … Electromagnetic induction is produced either by moving a magnet through a coil of wire on a substrate or by moving coils of wire passed stationary magnets.

## How do you explain electromagnetic induction?

Electromagnetic Induction is a current produced because of voltage production (electromotive force) due to a changing magnetic field. This either happens when a conductor is placed in a moving magnetic field (when using AC power source) or when a conductor is constantly moving in a stationary magnetic field.

## What is electromagnetic induction and how does it work?

Electromagnetic induction is the process of generating electric current with a magnetic field. It occurs whenever a magnetic field and an electric conductor move relative to one another so the conductor crosses lines of force in the magnetic field.29 мая 2019 г.

## What is electromagnetic induction class 10?

NCERT Electro Magnetic Induction Physics Chapter Note Class 10. The process of producing induced current in a closed circuit or in a coil by changing the magnetic field linked with the coil is known as electromagnetic induction.

## What is electromagnetic induction and what are its applications?

Today, electromagnetic induction is used to power many electrical devices. One of the most widely known uses is in electrical generators (such as hydroelectric dams) where mechanical power is used to move a magnetic field past coils of wire to generate voltage.

## What is the cause of electromagnetic induction?

Electromagnetic induction is where a voltage or current is produced in a conductor by a changing magnetic flux. Basic concept is When a charged particle travels through a magnetic field, it experiences a force F = qV X B. Because of movements in a particular direction induced EMF develop across the circuit.

## What are the two laws of electromagnetic induction?

Faraday’s Laws of Electromagnetic Induction consists of two laws. The first law describes the induction of emf in a conductor and the second law quantifies the emf produced in the conductor.

## What is the use of electromagnetic induction?

Then by either moving the wire or changing the magnetic field we can induce a voltage and current within the coil and this process is known as Electromagnetic Induction and is the basic principle of operation of transformers, motors and generators.

## Is electromagnetic induction AC or DC?

Uses & Design Differences. AC and DC generators both use electromagnetic induction to generate electricity. … But in a DC generator, a direct current flows in one direction. In an AC generator, the coil through which current flows is fixed and the magnet usually moves.

## How can we induce current in a coil?

Answer: The different ways to induce current in a coil are as follows: (i) If a coil is moved rapidly between the two poles of a horse-shoe magnet, then an electric current is induced in the coil. (ii) If a magnet is moved relative to a coil, then an electric current is induced in the coil.16 мая 2020 г.

## What is induction current?

The current induced in a conducting loop that is exposed to a changing magnetic field is known as induced current.

## What is called electromagnetism?

Electromagnetism is a branch of physics involving the study of the electromagnetic force, a type of physical interaction that occurs between electrically charged particles. … At high energy the weak force and electromagnetic force are unified as a single electroweak force.

## What is the principle of electromagnetism?

When a conductor is placed or moved through the magnetic field it generates voltage i.e., electricity. This principle is called Electromagnetic Induction. The voltages generated will be based on the speed of the conductor moving through the electric field.

## What are 3 uses for electromagnets?

• Motors and generators.
• Transformers.
• Pickups.
• Relays.
• Electric bells and buzzers.
