Today we made electromagnets by wrapping an iron nail with copper wire and attaching it to a battery. The nail became a magnet, because the battery sent energy through the copper wire, and gave the nail magnetic energy.
Reflection questions:
What is magnetism?
What does it mean to attract?
What does it mean to repel?
How do we use magnets?
How can you classify metals based on their magnetic properties?
