Accessible Classroom Model of Oersted's Law (the Right Hand Rule)

thingiverse

This model was created to assist high school teachers in teaching the mechanics of Oersted's Law (sometimes called "the right hand rule"). Oersted's Law describes the induction of a magnetic field around a current carrying wire. This phenomenon is easily visualized in experiments involving electric current and magnets, but these can be costly, hard to set up, and inaccessible to blind or partially sighted students. This model provides teachers with a cheaper, easier, and touch-based option for explaining Oersted's Law. To emulate Oersted's Law, the magnetic field represented in this model turns around a ratchet gear that permits rotation in only one direction. This model can be assembled without any adhesives or extra parts other than the files here.
