Repelling magnets appear to defy gravity when they are held close together. This “strong” force quickly weakens as the magnets move apart. In this experiment, students examine the force between repelling magnets to determine the mathematical relationship between the magnitude of magnetic force and the separation distance. For gravity, the relationship follows the inverse-square law. What relationship will dipole magnets follow? The results will surprise your students! By plotting the data, students will easily see the exponential relationship and will actually be able to calculate the exponential value. The experiment is easy to set up and perform, and students will be certainly become intrigued with the magnetic force. Includes background information, reproducible student handouts, and detailed Teacher Notes with sample data.
Super Value Kit is complete for 8 student groups. All materials are reusable! Support stands and spring scales are required for each lab group and are available separately.
