Ferrous metals

Answer 1

-These metals contain iron (ferrite).
-These metals are magnetic.
-these metals without a protective coating will rust if exposed to moisture.

Question 3

Non ferrous metals

Answer 3

-These metals do not contain iron (ferrite).
-These groups of metals are generally not magnetic.
