Jung dismissed the conspiracy claims made online about his video and said that his “visualizer is an electromagnet that moves a ferrofluid”, which is a magnetic substance.Ferrofluids, originally discovered in the 1960s at the NASA Research Center, according to the University of Wisconsin Madison ( here ), are a combination of magnetic nanoparticles, most commonly of magnetite, suspended in a carrier liquid. They have “the fluid properties of a liquid and the magnetic properties of a solid.” When in presence of a magnet, its tiny particles are drawn to it, causing an array of spikes.
