Grades 6–12. These fun experiments help you teach your students about Lenz's law and introduce them to Faraday's law of induction. With kit materials, students can build a galvanometer, explore real-world applications of Lenz's law, and more! Kit includes 5 experiments covering the properties of magnetism, 5 projects addressing Lenz's law, and instructions.
Grades 6–12. Teach your students about Lenz's law and introduce them to Faraday's law of induction with this series of fun experiments involving magnets free-falling within tubes. Watch how the magnets defy gravity as they fall down aluminum and copper tubes at different speeds. To illustrate Lenz's law, compare those speeds with the speed of magnets free-falling within a plastic tube. Build a galvanometer with kit materials to measure induced current. Finally, model real-world applications of Lenz's law such as eddy current braking used by some roller coasters and trains. Kit includes 5 experiments covering the properties of magnetism, 5 projects addressing Lenz's law, and instructions. Materials are sufficient for 2 to 3 students working as a group.
WARNING: Contains neodymium magnets. Neodymium magnets have a very strong magnetic field. Use with caution. Not for use by children under 14 yrs.
