Magnetic separation is a technique that uses magnets to separate magnetic solids from a mixture of non-magnetic solids. This method takes advantage of the fact that magnetic materials will be attracted to a magnet, while non-magnetic materials will not. One common example of magnetic separation is separating iron filings from salt using a magnet.
