Is Steel Magnetic? Other Metal Magnetic Questions Answered ...

Galvanized steel has a protective coating of zinc, which will not affect the magnetic properties of the steel, iron or other metal type that it is protecting. The zinc coating will not enhance the magnetic properties of the steel, but as long as the underlying metal is magnetic, the galvanized steel as a whole will have magnetic properties.

Ferromagnetism

Iron, nickel, cobalt and some of the rare earths (gadolinium, dysprosium) exhibit a unique magnetic behavior which is called ferromagnetism because iron (ferrum in Latin) is the most common and most dramatic example. Samarium and neodymium in alloys with cobalt have been used to fabricate very strong rare-earth magnets.
