Description
GSC International LNZLW Lenz’s Law Apparatus – Magnetic Induction and Electromagnetic Repulsion Demo – Open and Closed Loop Physics Tool with Instructions
The GSC International LNZLW Lenz’s Law Apparatus is a visually impactful demonstration tool used to teach electromagnetic induction and Lenz’s Law. The setup includes two metal hoops—one closed and one open—mounted on a central pivot point. When a bar magnet is introduced to the closed loop, an induced current and opposing magnetic field cause the loop to repel, illustrating the core principle of Lenz’s Law. In contrast, no effect is observed with the open loop, clearly showing the need for a complete circuit to induce current. This demonstration is ideal for physics classrooms, STEM education, or science fair presentations.
Electromagnetic Induction Demo: Demonstrates Lenz’s Law by showing how a changing magnetic field induces current in a closed loop
Open vs. Closed Loop Comparison: Closed loop reacts to a magnet with repulsion, while the open loop shows no response
Easy Classroom Setup: Freely moving hoops mounted on a central pin make it simple to observe effects of magnetic force
Includes Instructions: Comes with a user guide for clear setup, demonstration procedure, and teaching notes
Ideal for Physics & STEM: Great for science educators, homeschoolers, or science fairs to explore induction and field interactions
