The non-magnetic particles fall off straight from the magnetic roller as there is no attraction between them and the magnetic roller. Whereas the magnetic particles move a little more with the roller and fall at another place making them separated. Examples. A mixture of iron filling and sulphur powder can be separated by using a magnet.
