Liam, Emma, and Aiden are playing with a magnet. They are curious to know, the two poles of a magnet are called (a)   .

• East and West poles
• North and South poles
• Left and Right poles
• Mag and Net poles

Answer explanation

The two poles of a magnet are called North and South poles. These poles are responsible for the magnetic properties of the magnet.
