Cores and Coils Set allows students to study not only how transformers work, but also study several different properties of induced magnetism. This kit consists of a plastic base, a laminated iron core, mounting fixtures, and six coils protected in a heat resistant film. Topics covered include Lenz’ Law, Faraday’s Law, how iron cores increase magnetic field strength, and electromagnetic induction itself. This versatile piece of equipment can also be used to teach about how transformers used by power companies carry electrical energy. Extensive instructions on how to use the apparatus as a demonstration as well as inquiry-based lessons surrounding electromagnetic induction and transformers are included as well as five different student activity capture sheets. Please note that this set does not include all the materials necessary for the activities in the instruction manual.
