An electromagnet cannot be used for separating plastic bags from a garbage heap. This is because plastic bags are non-magnetic materials and electromagnet is used to separate only the magnetic materials.

Scrap iron can be separated from the heap, as it is a magnetic material. So, if we use an electromagnet, it can separate iron scraps from the heap.
