Acting at a distance, magnets pull on ferrous materials to attract or repel depending on the polar charge. While soft options are ideal for showing the forces of magnetism in a classroom setting, hard magnets are useful for picking up heavy metals. The devices are also commonly used to hang items for casual storage or for easy reference. Magnets come in different shapes and sizes based on specific task requirements.
