Features:<br /><br />Introduction on ferrofluid:<br />A ferrofluid is a liquid that becomes strongly magnetized in the presence of a magnetic field. Ferrofluids are colloidal liquids made of nanoscale ferromagnetic↔? or ferrimagnetic↔? particles suspended in a carrier fluid ( usually an organic solvent or water ). Each tiny particle is thoroughly coated with a surfactant to inhibit clumping. Large ferromagnetic particles can be ripped out of the homogeneous colloidal mixture↔? forming a separate clump of magnetic dust when exposed to strong magnetic fields.<br /><br /> <br />?
