Answer:
1.Magnetic metals
Iron is magnetic, so any metal with iron in it will be attracted to a magnet. Steel contains iron, so a steel paperclip will be attracted to a magnet too. Most other metals, for example aluminium, copper and gold, are NOT magnetic. Two metals that aren't magnetic are gold and silver
2.Materials that are not attracted to a magnet like air, wood, plastic, brass, etc., have a permeability of, essentially, 1. There is no magnetism induced in them by an external magnetic field, and therefore, they are not attracted by a magnet.

•Blocks, Trains and Other Toys. ...

4.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
