Ferromagnetic fluid moves to the beat of the music in the new Bluetooth speaker

Korean artist Dakd Jung has created a Bluetooth speaker that can render music using ferromagnetic fluid.

Ferromagnetic liquid is a liquid that is highly polarized in the presence of a magnetic field. Ferromagnetic fluids are colloidal systems consisting of ferromagnetic or ferrimagnetic nanosized particles suspended in a carrier fluid, which is usually an organic solvent or water.

Ferromagnetic fluid is highly polarized in the presence of a magnetic field, so Jung installed an electromagnet in the back of the device.

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.

When turned off, nothing happens to the magnetic material, but thanks to an electromagnet installed behind the glass container, the power is controlled by the Arduino Nano.

If you select low frequencies and turn on some kind of dance music, then the black matter will begin to change rhythmically.
