Coils and Cores Activity Set with AC/DC Power Supply, 6 Coils

This Coils and Cores Activity Set includes a plastic base with washer and nut for attachment, a laminated iron core with removable top, a thumbscrew and threaded rod, six coils (3200, 1600, 800, 600, 400, and 200 turns), an AC/DC regulated power supply, and an instruction and demonstration manual. The set allows students to study how transformers work and properties of induced magnetism, covering Lenz's Law, Faraday's Law, how iron cores increase magnetic field strength, and electromagnetic induction. Banana plug wires, multimeters, voltmeter, ammeter or galvanometer, ring stands, horseshoe magnet, paper clips, string, metal bars, bar magnets, springs, and tape are required for activities but not included. Suitable for physics classrooms studying electromagnetism.
