Electric forces exist among stationary electric charges; both electric and magnetic forces exist among moving electric charges. The magnetic force between two moving charges may be described as the effect exerted upon either charge by a magnetic field created by the other. From this point of ...
magnetic force on a current-carrying conductor solved examples frequently asked questions – faqs what is magnetic force? if we place a point charge q in the presence of both a magnitude field given by magnitude b(r) and an electric field given by a magnitude e(r) , then the total force...
In addition to current traveling through a wire, magnetism is produced by the spin magnetic moments ofelementary particles, such as electrons. Thus, all matter is magnetic to some degree because electrons orbiting an atomic nucleus produce a magnetic field. In the presence of an electric field, ...
In contrast to ferromagnetism, the forces of paramagnetism, diamagnetism, and antiferromagnetism are weak. In antiferromagnetism, the magnetic moments of molecules or atoms align in a pattern in which neighbor electron spins point in opposite directions, but the magnetic ordering vanishes above a certain...
Learn what a force field is. Explore the difference between a scalar and a vector field, and look at examples of force fields.
Central force is mainly experienced by the objects that are in a uniform circular motion as the force holds the object at a fixed point. Gravitational force and spring force are examples of central force
Magnetic forces originate in the motion of charged particles, such as electrons. The electrons "spin" around their axis and move in orbits around the nucleus of the atom to which they belong. Both motions generate tiny electric currents in closed loops that in turn create magnetic dipole fields...
What are Magnetic Poles? Magnets are a popular toy for children and can be used to explain the behavior of forces that are not visible. All matter, including magnets, is made of atoms. Each atom has a positively charged nucleus and electrons that orbit the nucleus, Atoms are made of ...
Field, in physics, a region in which each point has a physical quantity associated with it. The quantity could be a number, as in the case of a scalar field such as the Higgs field, or it could be a vector, as in the case of fields such as the gravitatio
