Electromagnetism is a branch of physics which deals with study of electromagnetic force. Being one of four fundamental interactions – along with gravitation, weak interaction and strong interaction – electromagnetic force happens between electrically charged particles. Discovered in the 19th century, elect...
In electricity, what is polarization? What is the meaning of equipotential? What is magnetism? Explain, with aid of a diagram, why lines of a force must be at right angles to equipotential contours? What is the difference between electromagnetic induction and electromagnetism? Are they closely co...
Electromagnetism, gravity, strong nuclear, and weak nuclear forces are the forces known to science. The strongest force of nature with the shortest range is the strong nuclear force.Answer and Explanation: Photons are known as the electromagnetic force carriers. The electromagnetic force is ...
the universe would have expanded outwards so quickly and with so much force that no stars or galaxies could have formed, or… there should be absolutely none. This means that the amount of vacuum energy in the cosmos must be much smaller than it is in these predictions. However, this discr...
Using this expression for the force, overall momentum (the sum of mechanical and electromagnetic momentum) is conserved in changing electromagnetic fields.doi:10.1088/1361-6404/aaa038FranklinJerroldEuropean Journal of Physics
If Coulomb's law is correct: F = mg tan θ The Importance of Coulomb's Law Coulomb's law is extremely important inchemistryand physics because it describes the force between parts of an atom and betweenatoms,ions, molecules, and parts of molecules. As the distance between charged particles...
The center of a black hole, where all of its mass is concentrated, is called the singularity. Gravitational Constant The gravitational constant (G) is a fundamental constant in physics that describes the strength of the gravitational force between two objects. It has a value of approximately ...
The voltage, orelectromotive force(emf), that results from the behavior of an electromagnet needs to be accounted for through techniques in physics and engineering to keep yourself and others safe. The current that flows through an electromagnet dictates how strong it is and, therefore, what sort...
magnetism. An electromagnetic wave consists of electric and magnetic waves running perpendicular to each other. Each component responds differently to frequency, voltage, current and distance, but with recent advancements in designing electronic systems, the E-field factor is mainly responsible for ...
