When a conductor is placed in a magnetic field and current flows in the conductor, the magnetic field and the current interact each other to produce force. The force is called “Electromagnetic force”. The fleming’s left hand rule determines the direction of the current, the magnetic force and the flux.
Where does the electromagnetic force come from?
The electromagnetic force governs all chemical processes, which arise from interactions between the electrons of neighboring atoms. There are numerous mathematical descriptions of the electromagnetic field. In classical electrodynamics, electric fields are described as electric potential and electric current.
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 is called electromagnetic force?
The electromagnetic force, also called the Lorentz force, explains how both moving and stationary charged particles interact. … The magnetic force acts between moving charged particles. This means that every charged particle gives off an electric field, whether or not it’s moving.18 мая 2018 г.
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 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. All the known forces of nature can be traced to these fundamental forces.
Is normal force an electromagnetic force?
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.
What would happen if there was no electromagnetic force?
Since electromagnetic forces are responsible for regular chemical bonds, every chemical compound would dissolve. All life and all ordinary objects would cease to exist. … Everything would be invisible, because light IS electromagnetism.
Why is it called electromagnetic?
Scientists call them all electromagnetic radiation. The waves of energy are called electromagnetic (EM) because they have oscillating electric and magnetic fields. … If it has low frequency, it has less energy and could be a TV or radio wave. All EM energy waves travel at the speed of light.
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.
Who invented electromagnet?
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.
Which is weakest force?
In nuclear physics and particle physics, the weak interaction, which is also often called the weak force or weak nuclear force, is the mechanism of interaction between subatomic particles that is responsible for the radioactive decay of atoms.
What is the strongest and weakest force?
Ordered from strongest to weakest, the forces are 1) the strong nuclear force, 2) the electromagnetic force, 3) the weak nuclear force, and 4) gravity.22 мая 2013 г.
Is love the strongest force on earth?
Einstein said, “If instead of E = mc2, we accept that the energy to heal the world can be obtained through love multiplied by the speed of light squared, we arrive at the conclusion that love is the most powerful force there is, because it has no limits.” …
