Lenz Law Demonstration Model Magnetic Field Induction Current Direction Loop Demo Tools 180x80x30mm

- This is a simple and effective way to demonstrate induction & lens law.

- The metal hoops (one open and one closed) are freely moving on a centrally mounted pin.

- The apparatus moves when a magnet passes through the closed loop and does not move when the loop is open, proving Lenz's law. Magnet not included.
