What is demagnetization?
Think about what happens when a magnet is heated or hammered.
True or False: Hammering a magnet can cause demagnetization.
Consider how physical impacts affect materials.
A permanent magnet is heated above its Curie temperature and then cooled. What happens to its magnetic properties? Explain why.
Consider the concept of thermal energy affecting alignment.
If a magnet is hammered multiple times versus being subjected to an alternating current, which method do you think would have a longer-lasting effect on demagnetization? Justify your answer.
Think about the constant effects of electrical currents versus occasional impacts.
