Placing it near a magnetic field
You can magnetize them by placing them near the magnetic field of a metal, this magnetizes them Another way to magnetize a ferromagnet it to wrap a insulated live wire around it, letting each end of the wire touch a + or - side of a bettery. This produces an electromagnet, and it can be turned on or off.
No.
You cannot magnetize a permanent magnet because it is already magnetized.

Generally, no you can't. A ferromagnetic material has what are called magnetic domains within it. These domains are effectively "tiny magnets" and are randomly arranged when they are in non-magnetized ferromagnetic metals. We can align them and make the material magnetic with the right equipment. A bit of metal that is not ferromagnetic has to domains to realign, so it can't be magnetized.
When a ferromagnetic substance is magnetized, the magnetic dipole moments of the atoms in the material line up in one direction and are able to produce a net magnetic field. This has to do with iron's elctron configuration on the atomic level.
Yes, steel is a ferromagnetic material.
