# What is the formula of electromagnetic force?

Contents

The force can also be written F = qE, or alternatively, the electric field can be expressed as E = F/q.

## What is the equation for electromagnetic force?

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.

## Where is electromagnetic force found?

The electromagnetic force is a force that occurs between electrically charged particles, such as electrons, and is described in electrostatics as being either positive or negative. Objects with opposite charges produces an attractive force between them, while objects with the same charge produce a repulsive force.

## What causes electromagnetic force?

The electromagnetic force is caused by the exchange of photons (effectively ‘particles’ of light) and the chance of photons being emitted or absorbed is related to the charge on an object.

## What is the magnetic field formula?

The magnetic field formula contains the c o n s t a n t μ 0 constant^{mu_{0}} constantμ0. This is known as permeability of free space and has a v a l u e 0 μ value^{mu}_{0} value0μ = 4 π × 1 0 − 7 ( T ⋅ m 4pi times 10^{ -7} (T cdot m 4π×10−7(T⋅m/ A).

## What are 4 types of force?

The Four Fundamental Forces of Nature

• Gravity.
• The weak force.
• Electromagnetism.
• The strong force.

## What does F BIL stand for?

F = BIL (f=force, b=magnetic field, i=current, l=length of conductor)

## What is range of electromagnetic force?

The electromagnetic force is a force of infinite range which obeys the inverse square law, and is of the same form as the gravity force.

## Is normal force electromagnetic?

The normal force is an everyday force that is felt when a surface pushes against an object that is placed on that surface. … The normal force arises from the electromagnetic force; specifically, the electrons in the book push against the electrons in the table.

## 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 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.

## 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.

## What are two kinds of electromagnetic forces?

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

## What is called magnetic field?

A magnetic field is a vector field that describes the magnetic influence on moving electric charges, electric currents, and magnetized materials. … The effects of magnetic fields are commonly seen in permanent magnets, which pull on magnetic materials such as iron, and attract or repel other magnets.

## Which unit is Tesla?

Tesla, unit of magnetic induction or magnetic flux density in the metre–kilogram–second system (SI) of physical units. One tesla equals one weber per square metre, corresponding to 104 gauss. It is named for Nikola Tesla (q.v.).
