Magnetic Domain:
Microscopic areas of atoms where the magnetic fields are aligned.

Ferromagnetic:
A naturally magnetic class of materials where the magnetic domains are ordered and do not cancel out.

Magnetic Field:
Lines showing the shape and exent of a magnetic field around a permanent magnet or a moving charged object.  To signify a field coming directly out of the plane of a page, dots are used.  To signify a field going directly into the page, an X is used.

Right Hand Rule. RHR:

1. The fingers extend or curl in the direction of the magnetic field.
   
2. The outstretched thumb points in the direction of conventional current, or the direction of a positively charged moving particle.
   
3. A line perpendicular to the palm indicates the direction of the magnetic force.

Mass Spectrometer:
A device that magnetically separates charged ions according to their mass.  A magnetic field is used to accomplish this separation.

Magnetism is a naturally occurring phenomena.  In most materials, the magnetic domains are randomly aligned.  However, in some cases, they are all aligned to produce a magnet.  This creates a magnetic field that extends around the object, moving from North to South.  A magnetic field can also be created from a moving charge, or current.  The right hand rule is used to visualize this field.  When a charge moves through an existing magnetic field, a magnetic force is exerted on it.  There are many examples in science and technology that utilize magnetism.
