P11 magnetism
This document discusses different magnetic materials like cobalt, iron, nickel, and steel. It explains that magnets have two poles called North and South and that the North pole of a magnet will line up with the geographic North pole of Earth when allowed to swing freely. The document also mentions induced magnetization can be temporary or permanent, as well as hard or soft. Additionally, it states that wrapping a wire carrying a current produces a magnetic effect around the wire, referring to electromagnets.
