Demountable Transformer Set – Complete Electromagnetic Induction Teaching Kit

This Demountable Transformer Coil Set provides a hands‑on, visual way for students to explore the principles of electromagnetic induction, transformers, and magnetic fields. Designed specifically for educational use, the kit allows learners to construct, dismantle, and investigate real transformer components, helping them understand not only how transformers work, but why.

The set includes a durable plastic base, a laminated iron core, secure mounting fixtures, and six interchangeable coils protected with heat‑resistant film for long‑lasting use. With these components, students can investigate a wide range of physics concepts including Lenz’s Law, Faraday’s Law, electromagnetic induction, and how iron cores increase magnetic field strength.

This versatile equipment is also perfect for demonstrating how power companies use transformers to transmit electrical energy efficiently across the grid. The kit comes with comprehensive instructions, demonstration guides, inquiry‑based lesson ideas, and five student activity sheets to support structured classroom learning.

For convenience and protection, the full set is supplied in a Gratnells Tray complete with a custom‑cut foam insert to keep each component securely stored.
