Exercise
Form 9: Properties of Permanent Magnets
In this engaging exercise, students will explore the fundamental properties of permanent magnets through hands-on activities and experiments, enabling them to understand concepts like magnetism strength, polarity, and the interaction between magnets and various materials. By the end of the session, students will be able to describe how these properties affect the everyday applications of magnets in technology and nature.
