The magnetic field is the region around a magnet where the magnetic forces are observable. It is defined by the presence of magnetic force on moving charges, which are experienced as attraction or repulsion. This field can be visually represented by field lines emanating from the north pole to...
The magnetic flux density or magnetic induction is the number of lines of force passing through a unit area of material, B. The unit of magnetic induction is the tesla (T). The magnetizing force, which induces the lines of force through a material, is called the field intensity, H (or ...
hysteresis- the lagging of an effect behind its cause; especially the phenomenon in which the magnetic induction of a ferromagnetic material lags behind the changing magnetic field physical phenomenon- a natural phenomenon involving the physical properties of matter and energy ...
The Magnetism of Magnets Wayne M. Saslow, in Electricity, Magnetism, and Light, 2002 9.10 How Permanent Magnets Get Their Permanent Optional Real magnets are not as simple as we have described them. Typically, they are very nonuniform unless they are in such a large magnetic field that they...
We love talking about magnets. When we do, we often use magnetic field pictures to show what's going on. There's a lot of information to be learned from these images, but let's take a moment and examine them more closely. What are those black lines circling around the magnet? What ...
FIG. 4ais a diagrammatic view of sector magnets used in the transmission of FIGS. 1,2,3aand3b, with curved magnetic lines of force illustrated as straight lines to show an approximate effective magnetic field. FIG. 4bis a diagrammatic view of ring-forming magnets used in the transmission of...
The magnetic hyperfine field is usually antiparallel to the magnetic moment of the iron ions. The electrostatic interaction between the electric quadrupole moment of a nonspherical nucleus and the electric field gradient due to the surrounding charges can result in shifts of the six lines of spectra...
The state of the pipe thus can be qualitatively monitored by the changes in the magnetic field strength. For instance, a sharp bending of the flux lines indicates a sharp, high-amplitude anomaly, which may refer to a crack in the pipe wall perpendicular to the field direction. A gradual ...
In cuprates, the Hall effect has been a powerful probe of theT = 0 field-revealed normal state (e.g. refs. 14,15,16,17,18,19and refs. therein). In the high-field limit asT → 0, the Hall coefficientRH, obtained from the Hall resistivityρyx(H) = RHH, can be...
