(c) Parallel magnetic lines of force traveling in the same
traveling in opposite directions tend to unite with each other
and form into single lines traveling in a direction determined
by the magnetic poles creating the lines of force.
(d) Magnetic lines of force tend to shorten themselves.
Therefore, the magnetic lines of force existing between two
unlike poles cause the poles to be pulled together.
(e) Magnetic lines of force pass through all materials, both
magnetic and nonmagnetic.
(f) Magnetic lines of force always enter or leave a magnetic
material at right angles to the surface.
e. Magnetic Effects.
(1) Magnetic Flux. The total number of magnetic lines of
force leaving or entering the pole of a magnet is called
MAGNETIC FLUX. The number of flux lines per unit area is known
directly related to the magnetic force exerted by the field.
(3) Attraction/Repulsion. The intensity of attraction or
repulsion between magnetic poles may be described by a law
almost identical to Coulomb's Law of Charged Bodies. The force
between two poles is directly proportional to the product of the
pole strengths and inversely proportional to the square of the
distance between the poles.
magnetic material by several means. The magnetic material may
magnet, or stroked by a magnet. Stroking and contact both
indicate the actual conduct of the material but are considered
in magnetic studies as magnetizing by INDUCTION.
It has been previously stated that all substances that are
attracted by a magnet are capable of becoming magnetized. The
fact that a material is
