Demonstration Induction Coil with Primary Coil, Demonstration Primary and Secondary Coil, Electromagnetic Induction Coil Experiment Instrument Physics Teaching Tool for Physics Teaching

["【INDUCTION COIL FOR LABORATORY】: Magnetic induction phenomenon coil kit includes 1 primary coil A, 1 secondary coil B and 1 soft iron core C, complete accessories, convenient for testing, the original coil is suitable for 3-4V DC power supply, use Safety","【GOOD ELECTRICAL CONDUCTIVITY】: Electromagnetic induction spiral coil is made of PVC pipe and brass wire material. Secondary coil and soft iron core cylindrical magnet PVC pipe has high hardness and is more sturdy. Demonstration primary and secondary coil brass wire has good electrical conductivity and better test results","【EASY TO CONNECT】: Induction coil used in the laboratory needs to connect the two ends of the secondary coil B with the two ends of the ammeter with wires, and is used with bar magnets, ammeters, sliding varistors and other instruments, easy to connect, convenient Observe the induced current in the coil","【DEMONSTRATION INDUCTION COIL】: Electromagnetic induction spiral coil primary coil bottom hole inner diameter 25mm, secondary coil bottom hole inner diameter 15mm, soft core length 85mm. Demonstration induction coil with primary coil is small size, easy to carry, easy to use","【APPLICATION SCENARIO】: Electromagnetic induction spiral coil for teaching can be widely used to study electromagnetic induction phenomenon, verify Lenz's law, and study the experiment of magnetic induction phenomenon. Secondary coil and cylindrical magnet is a very practical physics teaching tool"]
