    Pulley magnets are a wide rotating magnet that is just under the endof a conveyor belt. while pulley magnets also use a conveyor belt setup, the magnet is underneath the belt as opposed to above the passingmaterials. for example, as materials move along on the conveyor belt,the pulley magnet below will attract ferrous materials and dispersethem into a separate sorting bin. the non-ferrous materials, on theother hand, will reach the end of the conveyor belt and cascade intotheir own separate bin.

    Oil isnt magnetic, but suspending magnetic nanoparticles within the oil turns it into a magnetic liquid known as a ferrofluid. previous research efforts using ferrofluids typically involved pumping a water-and-ferrofluid mixture through a channel with magnets on the outside directing the flow of the water one way and the flow of the ferrofluid another. however, this technique will work only if the concentration of the ferrofluid is known beforehand and remains constant neither of which is possible in water contaminated by an oil spill.

    Magnetic separation is a process used to separate materials from those that are less or nonmagnetic. all materials have a response when placed in a magnetic field, although with most, the effect is too slight to be detected. the few materials that are strongly affected magnetised by magnetic fields are known as ferromagnetics, those lesser though noticeably affected are known as paramagnetics.
