Magnetism in metals is due to electrons flowing in the same direction, causing a magnetic field. Not all metals produce a magnetic field.
No, a ruby does not respond to magnet.
YES
all magnets attract ferrous metals (metals containing iron) and the opposite poles of another magnet.
Ferrous metals, such as: Iron (Fe) Cobalt (Co) and some alloys respond to magnetism. Aluminum responds to electromagnetic eddy currents.

A magnet is attracted by metals containing iron in their makeup, primarily steel.
It means if they are effected by a magnet. Ferrous metals are pulled by a magnet.
Not all metals are magnetic; for example, graphite and aluminum. Additionally, a non-metal may be a magnet; for instance, O2, or oxygen gas, is paramagnetic.
Materials which contain iron, generally. These metals that work with a magnet are generally called "Ferrous" metals
Metals not magnetic, but permeable will become magnets when near or touching a permanent magnet. You can stroke some metals in the same direction repeatedly on a magnet and make it a magnet.
