Mutual attraction
between the magnetic material or exclusion of a physical phenomenon.
Common magnetic materials are iron and magnet, and some steel. While the
general material and does not have magnetic material in a magnetic
field, however, still subject to slight magnetic effect, but must
generally be measured with special apparatus.
Magnetic force is due to motion of electric charges generated by the
fundamental forces. Maxwell's equations describe the sources and
behavior of such a force law (see also reference to Biot - Savart law).
When the charge or charged objects in motion will produce a magnetic
state. For example, "Electromagnetic Induction" is the e-move in the
circuit with the phenomenon; and "permanent magnet" is the e-fixed in
the sub-atomic phenomena caused by the spin movement. |
