Lenz's Law Demonstrator - Induced Current Tester -Physics Teaching Tool - Used for Students' Physics Experiment Equipment

1. PURPOSE: This product is mainly used in middle school physics teaching to explain and demonstrate Lenz's law experiments. 2. STRUCTURE: The product is composed of base, support rod, aluminum ring and so on. Weight: 55g Size: 6.5*9.5*19.5/2.5*3.7*7.6in 3. HOW TO USE: 1. When using, choose a windless environment, avoid magnetic fields, place the aluminum ring on the tip of the needle, and make it still. 2. Pass the bar magnet in the same direction from the closed ring several times to see the demonstrator slowly rotating. The magnet must be magnetized before use, too weak magnetism will affect the effect. 4. MAINTENANCE AND MAINTENANCE: When the instrument is not in use, protect the needle tip and pay attention to moisture to avoid oxidation of the aluminum ball.
