Types of Magnetism

Because of their ​ (a)   structures, different materials behave differently when placed in a magnetic field.

• atomic and molecular
• geometric
• chemical
• biological

​ (a)   refers to materials (magnets) that are ​ (b)   attracted to other magnets and generally stay magnetized even when they are removed from an ​ (c)  

• Ferromagnetism
• strongly
• external magnetic field

Ferromagnets form from (a)   in the atoms of the (b)   . ​ (c)   are ferromagnetic materials.

• unpaired electrons
• magnetic material
• Iron, cobalt, and nickel
• paired electrons
• non-magnetic substances
• gold, silver, and platinum

• Ferromagnets both ​ (a)   other ferromagnets

• attract and repel
• ignore
• dissolve
• compress

(a)   refers to materials that are weakly repelled by other magnets and are magnetic only when in an external (b)   .

• Diamagnetism
• magnetic field
• Ferromagnetism
• Electromagnetism
• Paramagnetism

​ (a)   have paired electrons that realign themselves when in a magnetic field, giving the material a slight magnetic property.

• Diamagnets
• Ferromagnets
• Paramagnets
• Superconductors

​ (a)   materials include ​ (b)   and some heavy ​ (c)   such as mercury and gold.

• water
• metals
• Diamagnetic

(a)   refers to materials that are weakly attracted to other (b)   and are magnetic only when in an external (c)   .

• Paramagnetism
• magnets
• magnetic field
• Diamagnetism
• non-magnetic materials
• electric field

Paramagnets have some ​ (a)   electrons. The electrons in paramagnets also realign themselves when in a magnetic field. Paramagnetic materials include ​ (b)   .

• unpaired
• magnesium, molybdenum, lithium
• paired
• gold
• copper

Only (a)   materials retain their magnetic properties when an external field is removed. (b)   materials are repelled and (c)   materials are attracted by other magnets.
