The magnetic field from a loop of current carrying wire in the plane of the page is directed out of the page. In which direction do the electrons in the wire loop move?( ) A.counterclockwise B.clockwise C.they all move to the right side of the loop D.they all move to the left ...
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
Calculate the magnetic force on a current-carrying conductor. Because charges ordinarily cannot escape a conductor, the magnetic force on charges moving in a conductor is transmitted to the conductor itself. Figure 1. The magnetic field exerts a force on a current-carrying wire in a direction ...
Fig. 13. Magnetic moment against magnetic field in typical ferromagnetic materials. Magnetic core memories were used in early mainframe computers, where a matrix of current carrying wires was used to program magnetic rings referred to as nuclei. Subsequent memory devices kept storing the information ...

> I use a copper or aluminum tube, is there a magnetic field inside it or not? Are we talking about the fieldin the empty/nonconducting area"inside" (*) of a hollow cylindrical conducting tube carrying current in the axial direction?
The structure of the magnetic field of an active region was represented as an ensemble of inductively coupled current-carrying magnetic loops interacting with each other. Each loop, in turn, was simulated by an equivalent electric circuit with variable parameters as a function of the shape, scale...
