Ferrofluid is a unique type of fluid that contains nanoscale magnetic particles (typically iron-based) suspended in a carrier liquid, which is usually an oil or water. When exposed to a magnetic field, these tiny magnetic particles become magnetized and can cause the fluid to exhibit distinctive behaviors, such as forming spikes or other patterns along magnetic field lines.
