MagnetismMagnetismI. Characteristics of Magnets

Magnetism Magnetic poles Magnetic forces Magnetic field Magnetic domain

A. MagnetismMagnetism

force of attraction or repulsion between unlike or like poles

due to the arrangement of electrons

closely related to electricity

B. Magnetic PolesMagnetic 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 ForcesMagnetic 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 FieldMagnetic Field

area around a magnet where magnetic forces act

field lines show direction of field (NS)

E. Magnetic DomainMagnetic Domain

groups of atoms with aligned magnetic poles

in a magnetized object, domains are all aligned
