RADT 142 Magnetism Test
Questions and Answers
Magnetic Classification of Matter - Answer-Ferromagnetic Materials
Paramagnetic Materials
Nonmagnetic Materials
Diamagnetic Materials
Ferromagnetic Materials - Answer--Materials that can be magnetized
-Exhibit strong magnetic properties
-Are strongly attracted to a magnet
Paramagnetic materials - Answer--Materials that are only weakly attracted to a
magnetic field
-Loosely influenced by a magnetic field
nonmagnetic materials - Answer--Materials unaffected by a magnetic field
Diamagnetic materials - Answer--Diamagnetic materials are weakly repelled by a
magnetic field. These materials cannot be magnetized and are not attracted to a
magnet.
-Most elements in the periodic table, including copper, silver, and gold, are diamagnetic.
Magnetic Force Field - Answer-•Lines of force (magnetic flux lines)
•Direction
-N to S outside the magnet
-S to N inside the magnet
Form a closed loop
Magnetism - Answer-Charged particles in motion exhibit magnetism
magnetic domain - Answer-accumulation of many atomic magnets
Nature of Magnetism - Answer-Magnetic materials are usually in a non magnetized
state
-domains in random arrangement
If domains align
-results in a magnetized material with a N to S orientation
-effectively one N pole and one S pole
