What is electric flux in physics? What is a diode? What is Pascal's law? What is the principle of electromagnetic induction? What is Newton's third law? What is the conservation of charge? What is a superconductor? Give one example of it. ...
According to the laws of physics, there are four fundamental forces that describe the reactions of particles, one of which is considered electromagnetic force, which results in electrostatic force under certain conditions. Electrostatic force between electrons and protons is one of the strongest forces...
In what ways are liquid and electrical circuits analogous? What is the principle of a galvanometer? What can be used to convert mechanical energy into electrical energy? How can one manipulate with the electromagnetic force? Is it possible? If yes, how?
Force is everywhere and it comes in a variety of sizes, directions, and type. We can define Force as the push or pull of an object. Learn Force definition, unit & types of Force with solved examples.
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...
What is Electromagnetism The branch of the physics that deals with the electromagnetic force and describes the relationship between charges & poles is known as theelectromagnetism. The emf (electromagnetic force) is caused by the two fields first one is electrical field and the second one is magne...
We show that attempts to modify the force on a magnetic dipole by introducing either hidden momentum or internal forces are not correct. The standard textbook result ${\\bf F=abla(\\bmu\\cdot B)}$ is correct even in the presence of time dependent electromagnetic fields. Using this expressi...
A magnet produces a vector field, the magnetic field, at all points in the space around it. It can be defined by measuring the force the field exerts on a moving charged particle, such as an electron. The force (F) is equal to the charge (q) times the speed of the particle times ...
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 ...
What is the new fifth force? New evidence suggests a tiny subatomic particle could break the known laws of physics, hinting at the existence of a fifth force of nature. The forces currently known to scientists aregravity, electromagnetism, the weak force and the strong force. ... ...
