2 cards from this section. Quick, good the night before a test.
Name a paramagnetic material.
Think of metals that might be weakly attracted to a magnet.
What happens to paramagnetic materials when the magnetic field is removed?
Recall their behavior when not under an external field.
Which of the following materials is paramagnetic?
Recall the definitions of different types of magnetic materials.
True or False: Paramagnetic materials retain their magnetism after the external magnetic field is removed.
Think about what happens when the field is turned off.
Explain how the concept of paramagnetism would change if the electrons in a material were fully paired. What would the implications be for its uses in technology?
Consider the roles of paired vs. unpaired electrons in magnetism.
Given a material with 6 unpaired electrons, calculate its potential for paramagnetism in relation to a material with 12 unpaired electrons. What assumptions do you need to make?
Consider how the quantity of unpaired electrons correlates with magnetic strength.
