A ferrofluid is a liquid that is highly polarized in the presence of a magnetic field.Ferromagnetic
A ferromagnetic fluid is highly polarized in the presence of a magnetic field, so Jung installed an electromagneton the back of the device's case.
According to the description of the device, its power changes depending on the tempo of the music being played. In this way, the black liquid can physically respond to certain frequencies in the melody.
In the off state, nothing happens to the magnetic material, but thanks to an electromagnet installed behind a glass container, the power of which is controlled by the Arduino Nano.
If you choose low frequencies and turn on some kind of dance music, then the black matter will begin to change rhythmically.
