 Magnetism
 Magnetic poles
 Magnetic forces
 Magnetic field
 Magnetic domain
A. Magnetism
 Magnetism
 force of attraction or repulsion between
unlike or like poles
 due to the arrangement of electrons
 closely related to electricity
B. Magnetic Poles
 Magnetic Poles- parts of the magnet where the
magnetic effects are strongest
 like poles repel
 unlike poles attract
 a broken magnet creates new poles
C. Magnetic Forces
 Magnetic force
 The force of repulsion or attraction
between the poles of magnets
 When magnets are close to each other
they will either pull together or push apart
D. Magnetic Field
 Magnetic Field
 area around a magnet where magnetic
forces act
 field lines show direction of field (NS)
E. Magnetic Domain
 Magnetic Domain
 groups of atoms with aligned magnetic
poles
domain
 in a magnetized object, domains are all
aligned
