This is the strongest magnetic material currently available. It is used in situations which demand a very thorough ferrous separation. Bakker Magnetics uses this material in systems for separating ferrous contamination from raw materials in which very small particles (μ range) are present or the types of steel to be extracted have weak magnetic properties. Neodymium magnets can also be used successfully for ferrous separation from viscous fluids. Neodymium is a rare earth material.
