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.Nov 10, 2017

As with all forces, electromagnetic force is measured in Newtons (N). The constant ​k​ has a specific value, 9 × 10⁹ N m² / C².Nov 2, 2020

Kids Definition of electromagnetic

: of or relating to a magnetic field produced by an electric current. electromagnetic.

• The electromagnetic force is one of the four fundamental forces. The electric force acts between all charged particles, whether or not they're moving. The magnetic force acts between moving charged particles. Moving charged particles (like those in electric current) give off magnetic fields.

• Formula: F = (n x i) 2 x magnetic constant x a / (2 x g 2) Where, F = Force, i = Current, g = Length of the gap between the solenoid and a piece of metal, a = Area n = Number of turns, Magnetic constant = 4 x PI x 10 -7 . Solenoid Coil Electromagnetic Force calculation is made easier here.

• electromagnetic force. The fundamental force associated with electric and magnetic fields. The electromagnetic force is carried by the photon and is responsible for atomic structure, chemical reactions, the attractive and repulsive forces associated with electrical charge and magnetism, and all other electromagnetic phenomena.

• Electromagnetism is a branch of Physics, deals with the electromagnetic force that occurs between electrically charged particles. The electromagnetic force is one of the four fundamental forces and exhibits electromagnetic fields such as magnetic fields, electric fields, and light.

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.Nov 10, 2017

Electromagnetism is the force that acts between electrically charged particles. This phenomenon includes the electrostatic force acting between charged particles at rest, and the combined effect of electric and magnetic forces acting between charged particles moving relative to each other.

The electromagnetic force is the force that causes an attraction between electrons and the positive nucleus. All forces between atoms are caused by the electromagnetic force.Jul 16, 2021

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.

Electromagnetic forces are responsible for holding atoms together in solids and liquids, creating friction forces that allow you to walk across the room, producing light and radio waves, generating electricity, and so much more! Electromagnetic forces are responsible for making this bulb give off light.

Potential difference is the energy released when the unit quantity of electricity passes from one point to another. The full form of EMF is Electromotive force. The cause is the Electromagnetic Field. ... Voltage developed by an electrical source is called electromotive force.

The equation is given by F = q v × B or F = qvB sin θ, where q is the charge, B is the magnetic field, v is the velocity, and θ is the angle between the directions of the magnetic field and the velocity; thus, using the definition of the cross product, the definition for the magnetic field is.

Without the electromagnetic force, atoms and molecules would never form. Electromagnetism is the force exerted by charged particles on one another. Electrons and protons are oppositely charged particles that react to both electric and magnetic fields.

The common designations are: radio waves, microwaves, infrared (IR), visible light, ultraviolet (UV), X-rays and gamma rays.Mar 12, 2015

Friction is the resistance to motion of one object moving relative to another. It is not a fundamental force, like gravity or electromagnetism. Instead, scientists believe it is the result of theelectromagnetic attraction between charged particles in two touching surfaces.Feb 12, 2020

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. All the known forces of nature can be traced to these fundamental forces.

• Engineers make solenoids - electromagnets - by twisting lengths of metal in a spiral fashion around a cylindrical template. You can determine the magnitude of that force by plugging the dimensions and other properties of the magnet based into a simple equation: F = (n X i) 2 X magnetic constant X a / (2 X g 2) .

• 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. More specifically the constant that links charge and the emission (or absorption) of a photon is called alpha, the fine structure constant.
