Super-strong magnets are making this approach to keeping coolant clean a very attractive option.
Recently, magnetic separation has experienced major technological advancements in the area of magnetic particle filtration for the metalworking industry. Increases in the strength of permanent magnets has been extraordinary, and the advent of rare-earth permanent magnets has allowed the design of high intensity magnetic circuits operating without electrical energy. Magnetic circuits designed with rare earth magnets now generate a magnetic force of an order of magnitude greater than the conventional ferrite magnets used only a few years ago.
The significance of the ...
