Webferromagnetic material, hematite- Fe 2 O 3. 1.1 Types of Magnetism Paramagnetism: In the absence of a magnetic eld, the magnetic moments of a paramagnet are oriented randomly due to thermal uctuations. When a magnetic eld is applied, they begin to align paralell to the eld and the magnetisation is proportional to the applied eld: ~˙= ˜B ... WebNano Magnetic Ferrofluid Description: Ferrofluids are composed of nanoscale particles (diameter usually 10 nanometers or less) of magnetite, hematite or some other compound containing iron. This is small enough for thermal agitation to disperse them evenly within a carrier fluid, and for them to contribute to the overall magnetic response of the fluid. the pit durham menu
