C1-100

Something that can exert a pull

or force on a piece of iron.

C1-200C1-100

This is revealed when iron filings

are sprinkled over a magnet.

These are the two poles of a

magnet.

C1-400C1-100The North end of a magnetic compass’ needle will point towards this bar

magnet pole.

C1-500

C1-100

The Earth’s South magnetic pole is near this geographic pole.

C2-100C1-100

This is where magnetism originates.

Groups of aligned atoms are called this.

C2-100C1-100

C2-300

Two out of three ways that a

permanent magnet can lose it’s magnetism.
