An electromagnetic pulsed-wave system having an electromagnetic boom for generating a time-varying pulsed-wave to control a colloidal mixture disposed in water and a depository. The electromagnetic boom comprising a plurality of electrically coupled solenoids disposed at the water for providing electromagnetic pulses to generate the time-varying pulsed-wave to transport the colloidal mixture. The depository having an electromagnetic ramp magnetically coupled with the electromagnetic boom and a separation receptacle for separating magnetized particles from the colloidal mixture.

A method is described for controlling an oil spill by seeding micron-sized magnetizable particles in the oil. Once seeded, particles can form a unique and preferential bond with the oil resulting in creation of a colloidal mixture. This bond forms as a result of a combination of forces including the intermolecular Van der Waal forces. Once this bond is formed, the oil is rendered magnetic and can be controlled and moved in response to a magnetic field. This can include removing oil from water, reducing the diffusion rate of oil on water, magnetically lifting oil from water or nonporous surfaces, as well as separating the magnetic material from the oil.

A magnet cleaner cooperates with one or more permanent magnets positioned over a conveyer carrying pieces of metal in non-ferrous material so as to remove the metal from the non-ferrous material. The magnet cleaner includes a frame and a capture sheet mounted to the frame and positioned on the frame so as to be substantially flush with the permanent magnets when they are in their lowered positioned. The magnets are spaced by an attenuation distance from the capture sheet when they are in their raised position. The permanent magnets, which may be mounted in a housing, are positionably mounted on the frame so as to be selectively elevatable between their lowered and raised positions upon actuation of an actuator. The actuator is positioned so as to cooperate with the permanent magnets and the frame so as to raise or lower the magnets relative to the capture sheet.

For the purpose of preparing and isolating diamagnetic nanoparticles, we add magnetic field into the preparation processes, so that impurities that can be attracted to a magnet will go to the magnetic source. This enables diamagnetic nanoparticles get purified and contain no such impurities, so that they will be pushed away from the magnetic source.

Some preparation processes use evaporation and condensation to prepare nanoparticles. In such processes, we may control the temperature so that lower evaporating metals, such as bismuth, will evaporate, but higher evaporating metals, such as iron, will stay solid and retain a strong magnetism, so that, when we apply magnetic field, we can prepare bismuth nanoparticles that do not contain lower evaporating metals for the preparation process.

A magnetic separation device has a membrane having a plurality of pores, a magnetically soft material layer disposed on the membrane, and a passivation layer disposed on the magnetically soft material layer. The magnetic separation device may be part of a microfluidic device having a lateral flow channel and a vertical flow magnetic separation filter. The magnetic separation device may be used to separate magnetically tagged particles, such as cells.
