It is studied in the scientific discipline known as electrostatics by researchers analyzing electromagnetic interaction. Specifically, electrostatic force is the physical reaction that holds together the electromagnetic field created by subatomic particles, such as electrons and protons. In order for ...
Voltage is the amount of power in the source and the resistance is the component in the circuit that resists the flow of current.Answer and Explanation: Electromotive force (e.m.f) can be defined as the source of energy like a battery or a generator in a circuit. E.m.f...Become a ...

Is magnetism a chemical property? What is the electromagnetic force? What is an induced magnetic field? Is magnetism a physical property? What is the magnetic field of a bar magnet? What is mu in Faraday's law? What creates a magnetic force?
Magnetism is a force of nature produced by moving electric charges. Sometimes these motions are microscopic and inside of a material known as magnets. Magnets, or the magnetic fields created by moving electric charges, can attract or repel other magnets, and change the motion of other charged ...
I don't think physicists really know the answer to that. They know that the electromagnetic field is actually made of an enormous number of photons, but do virtual, massless photons make up the magnetic field, and how does one field affect other magnetic fields at a distance, and does the...
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...
which in turn produces another varying magnetic field. The result is a "leapfrog" effect in which both fields can propagate over vast distances through space. Such a synergistic field is known as an electromagnetic field and is the phenomenon that makeswirelesscommunications, broadcasting and control...
Gravitational force. Electromagnetic Force. Weak Nuclear Force. Strong Nuclear force. The Four Forces of Nature 18 related questions found How many types of forces are there? There are2 typesof forces, contact forces and act at a distance force. Every day you are using forces. Force is basica...
fields. When an electric current passes through a conductor, a circular electromagnetic field is created around it. The direction of the current decides the direction of rotation of the created magnetic field. The current strength as well as length of the conductor decides the force of electromagne...
