# What is electromagnetic force Class 11?

Contents

Electromagnetic Force: It is the force between charged particles. Charges at rest have electric attraction (between unlike charges) and repulsion (between like charges). … Together they are called Electromagnetic Force.

## What is meant by electromagnetic force?

What is Electromagnetic Force? The electromagnetic force is a type of physical interaction that occurs between electrically charged particles. It acts between charged particles and is the combination of all magnetic and electrical forces. The electromagnetic force can be attractive or repulsive.

## What is electromagnetic force and its formula?

Lorentz force, the force exerted on a charged particle q moving with velocity v through an electric field E and magnetic field B. The entire electromagnetic force F on the charged particle is called the Lorentz force (after the Dutch physicist Hendrik A. Lorentz) and is given by F = qE + qv × B.

## What are the properties of electromagnetic force Class 11?

The properties of electromagnetic force are as follows:

• It obeys the inverse square law.
• It may be attractive or repulsive in nature.
• It is a long range force.
• The photon is the field particle of electromagnetic force.
• It is about 1036 times stronger than the gravitational force.

## Which best describes the electromagnetic force?

Which best describes the electromagnetic force? It is weaker than the gravitational force, with a greater range than the weak nuclear force.

## What is electromagnetic force quizlet?

electromagnetic force. the attraction or repulsion between charged particles. electromagnetic force holds negatively charged electrons to the positively charged nuclei of atoms.

## What is unit of electromagnetic force?

See all related content → Despite its name, electromotive force is not actually a force. It is commonly measured in units of volts, equivalent in the metre–kilogram–second system to one joule per coulomb of electric charge.

## Why is there an electromagnetic force?

Electromagnetic Force

The direction of magnetic flux produced by a permanent magnet is always from N-pole to S-pole. When a conductor is placed in a magnetic field and current flows in the conductor, the magnetic field and the current interact each other to produce force. The force is called “Electromagnetic force”.

## What is the example of electromagnetic force?

All of the light from the Sun and other sources consists of photons which are the electromagnetic force carriers. Magnets and the Earth’s magnetic field, which protects us from harmful radiation, are aspects of the electromagnetic force.

## What are the properties of electric and magnetic electromagnetic forces?

Key Takeaways: Electricity and Magnetism

Electricity and magnetism are two related phenomena produced by the electromagnetic force. Together, they form electromagnetism. A moving electric charge generates a magnetic field. A magnetic field induces electric charge movement, producing an electric current.

## Which is stronger the strong force or the electromagnetic force?

As its name suggests, the strong force is the strongest—it’s 100 times stronger than the electromagnetic force (which binds electrons into atoms), 10,000 times stronger than the weak force (which governs radioactive decay), and a hundred million million million million million million (1039) times stronger than gravity …

## Is the electromagnetic force weaker than the weak force?

The most dramatic difference between the weak force and the electromagnetic force is in its strength. As its name would imply, the weak force is much weaker than electromagnetism or the strong force.

## Which is the strongest of the four fundamental forces?

The strong nuclear force, also called the strong nuclear interaction, is the strongest of the four fundamental forces of nature.
