we need to use magnetism when we need to separate substance attracted to magnets from other substance.
we need to use filtration when we need to separate a solid subs from a liquid subs.
Explanation:
Mixtures containing substances that are attracted by magnets can be separated using a magnet. We can separate iron from a mixture of sand and iron, as only the iron is attracted to the magnet.
Filtration is used to separate a solid from a liquid in which it is suspended. Filtration is also used to separate a substance from a mixture because one is insoluble in the solvent and the other is soluble. the separation is due to particle size.
