They remain parallel to one another

They are separate and individual forces, since one line will never cross another;

they actually repel one another.

attraction of unlike poles and repel unlike polse

There is no known insulator for magnetic flux, or lines of force

The magnetic fields of the two magnets do not combine, but are rearranged into a distorted flux pattern.The magnetic fields of the two magnets do not combine, but are rearranged into a distorted flux pattern.

called the north and south poles of the magnet

When a magnetizing force is applied to a piece of magnetic material, a point is reached where no more lines of force can be induced or introduced.

diamagnetic since they are repelled by both poles of a magnet.

ferrous materials;

nonferrous

opposition to the lines of force through a material, can be compared to the resistance of an electrical circuit

. The reluctance of soft iron, for instance, is much lower than that of air.

The magnetomotive force, causing lines of force in the magnetic circuit, can be compared to the electromotive force or electrical pressure of an electrical circuit.

measured in gilberts,(F)

the intensity of the lines of force, or flux, is the Greek letter (phi)

the unit of field intensity is the gauss

An individual line of force, called a maxwell,

there is a direct relationship between the intensity of the magnetizing force and the amount of magnetism developed in a material a

Subtopic

as the magnetizing force is increased, the flux density (magnetic field) increases

magnetically saturated

The faster the rate of change in the conductor magnetic field, the greater the eddy currents
