We will explore magnetic field configurations and field strengths for permanent magnets in this inquiry exercise. Students will observe the curved field lines around a permanent magnet, and explore how field strength varies with distance. They will observe the magnetic field created by a current-carrying wire, as well as the current created in a wire when a magnet moves past it.
