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.
Where is electromagnetic force used?
The electromagnetic force governs all chemical processes, which arise from interactions between the electrons of neighboring atoms. Electromagnetism is very widely used in modern technology, and electromagnetic theory is the basis of electric power engineering and electronics including digital technology.
Where does the electromagnetic force come from?
Electromagnetic forces arise from the exchange of virtual photons, where photon is the name given to a quantum or energy packet of the electromagnetic field.
Which is an example of the 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 is a electromagnetic force in physics?
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.
Who discovered electromagnetic force?
The discovery of electromagnetic induction was made almost simultaneously, although independently, by Michael Faraday, who was first to make the discovery in 1831, and Joseph Henry in 1832.
What are the common names for electromagnetic forces?
The electromagnetic force, also called the Lorentz force, explains how both moving and stationary charged particles interact. It’s called the electromagnetic force because it includes the formerly distinct electric force and the magnetic force; magnetic forces and electric forces are really the same fundamental force.
What forces are electromagnetic in nature?
As its name indicates, the electromagnetic force consists of two parts: the electric force and the magnetic force. At first, physicists described these forces as separate from one another, but researchers later realized that the two are components of the same 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 difference between electric force and magnetic force?
Magnetic forces and electric forces are two forces that occur in nature. Electric forces are the forces that occur due to electric charges whereas magnetic forces are the forces that occur due to magnetic dipoles.
What is electromagnetic force in easy language?
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.
Is electricity electromagnetic force?
electromagnetism, science of charge and of the forces and fields associated with charge. Electricity and magnetism are two aspects of electromagnetism. Electricity and magnetism were long thought to be separate forces.
Why friction is electromagnetic force?
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 the electromagnetic attraction between charged particles in two touching surfaces.
