What is a magnet? - Teacher's Notes

A magnet is a material or object that produces a magnetic field, which is invisible but responsible for the most notable property of a magnet: the force that pulls on other ferromagnetic materials, like iron, and attracts or repels other magnets. In educational settings, pupils are often encouraged to explore the concept of magnetism through multimedia resources such as the BBC Bitesize website. These resources help students understand not only what a magnet is but also which metals are magnetic and how magnetism can be applied in real-world scenarios, such as in scrapyards where large magnets are used to sort and move magnetic materials.

Interestingly, not all metals are magnetic. While we typically associate magnetism with metallic objects, metals like aluminium, copper, and gold do not exhibit magnetic properties. On the other hand, metals containing iron, such as steel, demonstrate magnetic qualities and will be attracted to magnets. This is why a steel paperclip, for example, can be picked up by a magnet. In the classroom, pupils are encouraged to engage with their peers in discussions about magnetism, compile questions on the topic, and test each other's understanding of magnets and their properties. This interactive approach to learning allows pupils to delve deeper into the science of magnetism and consider its practical applications in everyday life.
