Answer:
The use of a bar magnet is one of the simplest and easiest ways of physical separation of magnetic substances from non-magnetic substances. This is done by passing the magnet over the mixture when it will pick the magnetic substance out of the mixture
Explanation:
Magnetic separation is the process of separating components of mixtures by using magnet to attract magnetic materials.[1] The process that is used for magnetic separation detaches non-magnetic material with those that are magnetic. This technique is useful for not all, but few minerals such as ferromagnetism/ferromagnetic (materials strongly affected by magnetic fields) and paramagnetic (materials that are less affected) but the effect is still noticeable).[2] Not all metals are magnetic; gold, silver and aluminum are some examples.
