A. The compass accuracy is effected by hard iron (material that can become magnetized like Iron and Nickel) and soft iron (material that can distort magnetic fields but not before being magnetized).

How does a compass work simple explanation?

A compass works by detecting the Earth’s natural magnetic fields. … This allows the needle to better react to nearby magnetic fields. Since opposites attract the southern pole of the needle is attracted to the Earth’s natural magnetic north pole. This is how navigators are able to discern north.
