Hillary and I have an idea:
Title: Barkhausen Effect
Physics principles involved: Magnetic domains, electromagnetic
induction, magnetism.
Parts needed:
-Amplifier
-Speaker
-Inductor (must be hollow)
-Ferromagnet/Iron bar (must fit in inductor)
-Another permanent magnet
For amp and speaker, a guitar amp could work, but that might be a
little loud.
