Product Description Product DescriptionElectromagnetic induction coil teaching instrument1. Purpose: The product is mainly used in junior high school physics teaching demonstration. When part of the conductor of the closed circuit moves the magnetic inductive line in the magnetic field, current will be generated in the conductor. This phenomenon is called electromagnetic induction. The essence is the change in magnetic flux in a closed circuit. The current generated by electromagnetic induction in the closed circuit is called the induced current. 2. Composition: It consists of a single-turn coil and a four-turn coil. The coil is fixed on the insulating plate, and is connected to the red and black terminals. There are fixed sockets on the insulating plate, which can be matched with the square seat bracket horizontally or perpendicular to the vertical pole. 3. Method of use: (1) Fix the product on the square seat bracket or other fixed positions, connect the terminal on the single-turn coil to the input end of the micro current amplifier (self-provided). Connect the output end of the micro current amplifier to the demonstration meter (G) setting, adjust the potentiometer to the maximum, and then use a magnet (085,082,180 type) to intersperse back and forth in the coil to perform movement of cutting the magnetic inductive wire, observe the ammeter instructions, and find that a weak current is generated. (2) Replace the single-turn coil with four-turn coil and repeat the experiment above. Observe the ammeter instructions and find that the current generated is significantly larger. Therefore, it can be seen that the more coils, the greater the current generated is because the magnetic flux becomes larger.Detailed PhotosCompany Profile Packaging & ShippingFAQ
