As a music lover, I have always sought ways to visualize music.
After I learned about Ferrofluids, it finally occurred to me:
-Electromagnets can attract Ferrofluids.
-Electrical signals can control electromagnets.
-Music can be converted into electrical signals by Pickups.
After combining all these, I finally made this Ferrofluid speaker.
When music is playing, the ferrofluid inside the speaker pulses to the music's current rhythm.
