# What is the meaning of electromagnetic force?

Contents

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.

## What does electromagnetic force do?

The electromagnetic force is responsible for most of the interactions we see in our environment today. The EMF holds electrons in their orbit around the nucleus. These electrons interact with other electrons to form electron bonds among elements and produce molecules and, eventually, visible matter.

## What are the different types of electromagnetic force?

There are actually two general types of electromagnetic forces: electrostatic forces and magnetic forces.

## What is the formula for electromagnetic force?

Charges confined to wires can also experience a force in a magnetic field. A current (I) in a magnetic field ( B) experiences a force ( F) given by the equation F = I l × B or F = IlB sin θ, where l is the length of the wire, represented by a vector pointing in the direction of the current.

## What are 3 examples of electromagnetic energy?

They include:

• TV waves.
• Light.
• Ultraviolet Light (This is what causes Sunburns)
• X-rays (Just like the kind you get at the doctor’s office)
• Short waves.

## Which force is the strongest force?

The strong nuclear force, also called the strong nuclear interaction, is the strongest of the four fundamental forces of nature. It’s 6 thousand trillion trillion trillion (that’s 39 zeroes after 6!) times stronger than the force of gravity, according to the HyperPhysics website.

## Which best describes the electromagnetic force?

Electromagnetic force is the force which causes electric and magnetic effect such as repulsion between like charges or between two like poles of a magnet. This forces is long ranged and stronger with infinite range. It can be attractive or repulsive.

## What are the 4 fundamental forces?

Fundamental force, also called fundamental interaction, in physics, any of the four basic forces—gravitational, electromagnetic, strong, and weak—that govern how objects or particles interact and how certain particles decay.

## What are the characteristics of electromagnetic force?

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 force is a non contact force?

A non-contact force is a force which acts on an object without coming physically in contact with it. The most familiar non-contact force is gravity, which confers weight. … Gravity, the force of attraction that exists among all bodies that have mass. The force exerted on each bo the distance between them.

## How strong is the electromagnetic force?

It is very strong and this is surprising too because it can work over an infinite range. To give you an idea, the electromagnetic force is approximately 1036 times stronger than the earth’s gravitational field!

## Is electromagnetic a energy?

Electromagnetic (EM) radiation is a form of energy that is all around us and takes many forms, such as radio waves, microwaves, X-rays and gamma rays. Sunlight is also a form of EM energy, but visible light is only a small portion of the EM spectrum, which contains a broad range of electromagnetic wavelengths.

## How do we use electromagnetic energy?

Up to the end of the microwave spectrum, most all modern conveniences that use electromagnetic energy in one way or another are in the lower frequency region, including millimeter waves, cell phones, WiFi, microwave ovens, space and terrestrial communications, radar for airports and military uses, AM and FM radio, …

## What are the sources of electromagnetic energy?

Examples of EM radiation include radio waves and microwaves, as well as infrared, ultraviolet, gamma, and x-rays. Some sources of EM radiation include sources in the cosmos (e.g., the sun and stars), radioactive elements, and manufactured devices. EM exhibits a dual wave and particle nature.
