About This

• SUITABLE FOR: This current magnetic field demonstrator kit is widely used in kids science projects, physics or mechanical learning, classroom experiment demonstration, etc. This kit can be used to observe the shape and direction of current magnetic field ground induction lines, learn left and right hand rules, etc.
• PROJECTABLE TYPE: The current magnetic field demonstrator is projectable type that helps students clearly observe the demonstration process and results. This kit includes linear current magnetic field, solenoid current magnetic field, and loop magnetic field, easy to assemble and operate.
• HIGH QUALITY MATERIAL: These demonstration tool shells are made of excellent PVC material, with good toughness and impact resistance, transparent and intuitive.
• HOW TO USE: First put 4 small magnetic needles on the transparent plastic board, turn on the voltage (6‑8VDC), you can find the magnetic needle deflection, and then replace the magnetic needle with iron chips to experiment, also can come to the conclusion that there is a magnetic field around the DC conductor.
• NOTICE: 1. Do not with corrosive products such as acid and alkali when stored after use, keep dry, so as to avoid the oxidation of terminals and affect the experimental effect. 2. The instruments are made of transparent plastic. Do not handle them violently.
