|
ELECTROSTATIC LINES
|
A graphic representation of the field around a charged body.
|
|
|
MAGNETISM
|
That property of a material which enables it to attract pieces of iron.
|
|
|
FERROMAGNETIC MATERIALS
|
Materials that are easy to magnitize; iron steel and cobalt.
|
|
|
NATURAL MAGNETS
|
Magnetite, Lodestones, or leading stones.
|
|
|
RELUCTANCE
|
The opposition of a material being magnetized.
|
|
|
RETENTIVITY
|
The ability of a material to retain magnetism.
|
|
|
A MAGNETIC POLE
|
Located at each end of a magnet. Magnetic force is equal at both poles.
|
|
|
MAGNETIC FLUX
|
The total number of magnetic lines of force leaving or entering the pole of a magnet.
|
|
|
FIELD INTENSITY
|
The intensity of a magnetic filed is directly related to the magnetic force exerted by the field.
|
|
|
ATTRACTION / REPULSION
|
The intensity of the attraction or repulsion between magnetic poles. 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.
|
|
|
RESIDUAL MAGNETISM
|
The amount of magnetism which remains in a temporary magnet.
|
|
|
RENTENTIVITY
|
The ability of a material to retain an amount of residual magnetism.
|
|
|
MAGNETISM
|
In addition to the electrical charge on an electron, theres also a magnetic field.
|
|
|
ELECTRO MAGNETIC FIELD
|
When an electron recieves enough energy to free it from an atom an ELECTRO MAGNETIC FIELD OF FORCE develops as a ring around the moving electron that is perpendicular to its direction of motion.
|
|
|
ELECTRICAL ENERGY
|
When a difference of potential exists between two charged bodies that are connected by a conductor, electrons will flow along the conductor.
|
|
|
CONDUCTANCE
|
The opposite of resistance. The ability of material to pass electrons.
