About This

• [Scope of application]: This current magnetic field demonstrator kit is widely used in children's science projects, physical or mechanical learning, classroom experimental demonstrations, etc. The kit can be used to observe the shape and direction of the induction line of the current magnetic field, learn the left and right hand rules, etc.
• [Projectable type]: The current magnetic field demonstrator is a projectable type, which can help students clearly observe the demonstration process and results. The kit includes linear current magnetic field, solenoid current magnetic field and circular magnetic field, which are easy to assemble and operate.
• [High-quality materials]: The shells of these demonstration tools are made of high-quality PVC material, which has good toughness and impact resistance, and is transparent and intuitive.
• [How to use]: First put 4 small magnetic needles on a transparent plastic plate, turn on the voltage (6-8VDC), and you can find that the magnetic needle deflects, then use an iron sheet instead of a magnetic needle for the experiment, and you can also draw the conclusion that there is a magnetic field around the DC conductor.
• [Precautions]: 1. After use, do not contact with corrosive substances such as acids and alkalis, keep dry, so as not to oxidize the terminals and affect the experimental results. 2. The instrument is made of transparent plastic material, please do not operate violently.
