... Ferromagnetism A typical piece of iron is divided into small regions, typically less than 100 m in size, called magnetic domains. The magnetic moments of all the iron atoms within each domain are perfectly aligned aligned, so each individual domain is a strong magnet. However, the various ma ...

... Suggested answer: Students should explain that all magnets have a north and a south pole. The red end of the needle is the needle’s north pole, which always points north because it is attracted to the earth’s magnetic south pole as opposite magnetic poles attract. Thus, it can be concluded that the ...
