About This

• Versatile Physics Teaching & Experiment Tool This current magnetic field demonstrator kit is widely used for kids' science projects, physics learning, mechanical education, and classroom experiment demonstrations. Ideal for observing the shape and direction of magnetic field induction lines around current-carrying conductors and learning essential concepts like left-hand and right-hand rules.
• Projectable Design for Clear Classroom Observation The current magnetic field demonstrator features a projectable type design that allows students to clearly observe demonstration processes and results in real time. The kit includes experiments for linear current magnetic fields, solenoid current magnetic fields, and loop magnetic fields—all easy to assemble and operate.
• High-Quality Transparent PVC Construction These demonstration tool shells are crafted from premium PVC material offering excellent toughness and impact resistance. The transparent design provides intuitive visual access to internal components, enhancing student comprehension during experiments.
• Simple Step-by-Step Experimental Procedure First, place 4 small magnetic needles on the transparent plastic board and apply 6-8V DC voltage to observe magnetic needle deflection. Then replace the needles with iron filings to further demonstrate the presence of a magnetic field around DC conductors—providing clear, repeatable experimental results.
• Storage & Handling Guidelines for Longevity 1. After use, store away from corrosive substances like acids or alkalis and keep dry to prevent terminal oxidation that may affect experimental results. 2. The instruments are made of transparent plastic—avoid rough handling to maintain integrity and performance.
