# What is meant by 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. The electromagnetic force can be attractive or repulsive.

## 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.

## How do you explain electromagnetism?

The word “electromagnetism” in physics is used to describe one of the fundamental forces of nature. This force is between subatomic particles such as protons and electrons. It helps to hold matter together. Electromagnetism is also used to describe how a magnetic field is created by the flowing of electric 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.

## 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.

## 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 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.

## What is the unit of magnetic field?

The unit of electric field in the MKS system of units is newtons per coulomb, N/C, while the magnetic field (in teslas) can be written as N/(C·m/s). The dividing factor between the two types of field is metres per second (m/s), which is velocity.

## What causes electromagnetism?

Electromagnetism is produced when an electrical current flows through a simple conductor such as a length of wire or cable, and as current passes along the whole of the conductor then a magnetic field is created along the whole of the conductor.

## Where is electromagnetism used?

Electromagnets are widely used as components of other electrical devices, such as motors, generators, electromechanical solenoids, relays, loudspeakers, hard disks, MRI machines, scientific instruments, and magnetic separation equipment.

## How does electromagnetism affect our daily life?

Exposure to electric, magnetic and electromagnetic fields (EMF), if they are strong enough, can lead to short term health effects. Exposure to low frequency fields that are strong enough can lead to dizziness, seeing light flashes and feeling tingling or pain through stimulation of nerves.
