Magnetism Learning Area
Magnet is a material
capable of attracting iron and producing a magnetic
field. By the end of the 19th
century, all known elements and many compounds had
been tested for magnetism, and all were found to
have some. However, only three
elements—iron, nickel, and cobalt—present
ferromagnetism.
Magnets produce a
magnetic field of their own. Extreme examples of
magnets are (1) hard or permanent magnets, which
remember how they have been magnetized, and (2) soft
or impermanent magnets, which lose memory of
previous magnetizations. Soft magnets are often used
in
electromagnets to enhance the magnetic field of
a current-carrying wire that has been wrapped around
the magnet. Permanent magnets
occur naturally in some
rocks, but they are now more commonly
manufactured.
Materials without a
permanent magnetic moment can, in the presence of
magnetic fields, be attracted, or repelled.
Paramagnets tend to intensify the magnetic field in
their vicinity, whereas diamagnets tend to weaken
the magnetic field in their vicinity. Soft magnets,
attracted to magnetic fields, can be thought of as
paramagnetic; superconductors, repelled, can be thought of as diamagnetic.

Hall effect and Current Measurement
Discovered in 1879 by
Edwin H. Hall (1855 – 1938), the Hall field results from the force
exerted by the magnetic field on the moving particles of the current.
The Hall effect can be used to measure certain properties of current
carriers as well as to detect the presence of a current on a magnetic
field.

In "A", the Hall element takes on a negative charge at the top
edge (blue color) and positive at the lower
edge (red color). In "B" and "C", either the electric current or
the magnetic field is reversed, causing the polarization to
reverse. Reversing both current and magnetic field ("D") causes
the Hall element to again assume a negative charge at the upper
edge.
