magnetic force, attraction or repulsion that arises between electrically charged particles because of their motion. It is the basic force responsible for such effects as the action of electric motors and the attraction of magnets for iron. Electric forces exist among stationary electric charges; both...
magnetic force- attraction for iron; associated with electric currents as well as magnets; characterized by fields of force magnetic attraction,magnetism attraction,attractive force- the force by which one object attracts another electromagnetism- magnetism produced by an electric current; "electromagnetism...
Inducing Electric Current An electric field is induced only when a wire crosses the magnetic field lines. An electric current is induced because a magnetic force can cause electric charges to move. Electric Generator uses electromagnetic induction to change mechanical energy into electrical energy. the...
The force exerted on one electric current by the magnetic field of a second current has been calculated. This result is used to define the ampere in terms of the force between two parallel current-carrying conductors.doi:10.1016/B978-0-12-059860-1.50038-2George B. Arfken...
During your childhood, have you ever accidentally touched a light switch and suddenly experienced a jolt of electricity? Why and how this happens? What exactly are the heating and magnetic effects of electric current? Let's find out.
Does the magnetic force affect acceleration? Is the electric force stronger than the magnetic force? Is magnetism a push or pull force? Is the magnetic force contact or non-contact? Is the magnetic force in same direction of current?
With simple structure, reliable work, constant current and electric power saving, the utility model is suitable for frequent starting works without needs of maintenance and special speed adjusting control, the utility model is one of pivotal devices for realizing automation of the auxiliary well heads...
transient electro-motive force and electric current in a conducting loop on the surface of the illuminated material, and hence a transient magnetic field. ... Kruglyak,V Volodymyr - 《Journal of Nanophotonics》 被引量: 14发表: 2007年 THE EFFECTS OF CURRENT HELICITY AND SHEAR ON THE MEANELECTRO...
Magnetic field, a vector field in the neighborhood of a magnet, electric current, or changing electric field, in which magnetic forces are observable. Magnetic fields such as that of Earth cause magnetic compass needles and other permanent magnets to lin
the magnetic gradient force can be used to control and manipulate the flow and possibly influence the mass transfer. This is a departure from our previous work using this same microfluidic chamber17,22, which focused on manipulation of flow by changing the ionic current density by varying electron...
