Quick Answer:The Lenz’s Law – Open & closed loop apparatus teaches Faraday's law of induction and Lenz's law: a magnet passed through the complete loop makes the device move, while the split loop does not move at all.
Last updated: 18 October 2026
Key Features
Demonstrates Faraday's law of induction and Lenz's law.
Complete loop moves when a magnet passes through it.
Split loop shows no movement, for comparison.
Loops: Closed (complete) loop and open (split) loop
How It Is Used
A magnet is pushed through each loop in turn. Current induced in the closed loop opposes the magnet's motion and makes the device move, while the split loop, in which no current can flow round, stays still.
Frequently Asked Questions
Why does the split loop not move in the Lenz’s Law – Open & closed loop apparatus?
No current can circulate in the split loop, so no movement occurs; passing a magnet through the complete loop, by contrast, makes the device move.
Laboratories and education suppliers in Belize, Central African Republic, Cambodia, Moldova, Angola and Dominican Republic can source the Lenz’s Law – Open & closed loop from JLab India for export.
