Feature:1. Contains a variety of electromagnetic experiments, so that the content is no longer single.2. The experimental equipment is interesting and can help students understand the principles of the experiment faster.3. Made of highquality ABS material, the equipment is of good quality and not easily damaged.4. This standard version physical electricity and magnetism kit is synchronized with compulsory education textbooks, which is convenient and practical.5. Especially suitable for elementary school students, it is a good experiment kit to stimulate interest in exploration.Specification:Item Type: Electricity Magnetism Learning KitMaterial: ABSBattery: 2 x 1.5V AA batteries (battery not included)Purpose: Elementary School Science Electromagnetic ExperimentHow to Use:1. Light up the small bulb experiment.Observe the structure of the small light bulb, connect one section of the wire to the connection point of the small light bulb, connect the other end to the negative electrode of the battery, and then connect the connection point of the small light bulb to the positive electrode of the battery. Then observe whether the small bulb is on.Note: Never directly connect the wires to the positive and negative poles of the battery, as this will short-circuit the battery and generate heat and is flammable.2. Simple circuit connection.First fix the small bulb with the small bulb socket. In order to make the bulb reach the normal brightness, we need to connect 2 AA batteries in series to control the on and off of the bulb, and add a switch in series to the circuit.3. Homemade traffic lights.First, connect the positive pole of the battery pack to the red hat port of the SPDT switch with a wire, and connect 2 wires from the black hat port of the switch to the red hat port of the LED socket, and then connect it from the black hat port of the LED socket 2 wires are connected to the negative pole of the battery pack. In this way, the self-made traffic light experiment can be completed.4. Homemade electromagnet.Use an AA battery and connect the enameled coil to the positive and negative poles of the battery. Try to attract small nails using electromagnets.Note: Do not power on for a long time! Note that the electromagnet is hot!5. Get to know the hand-cranked generator.Use 2 wires to connect the hand-cranked generator and the lamp holder with the bulb. When the hand-cranked power is generated, you can feel the speed when the bulb is normally on.6. Verify the unidirectional conductivity of the LED with a hand-cranked generator.First, connect the positive and negative poles of the red and green lights to the ends and connect them in series to prevent the generator voltage from burning out the LEDs, and then connect the generator wires to the remaining 2 terminals. Shake the generator clockwise or counterclockwise and observe the situation of LED' turning off and turning on..Package List:2 x Battery Box3 x Small Bulb4 x Electromagnet1 x Enameled Coil1 x Iron Nail1 x Compass1 x Fan Blade1 x Magnetic Powder Box1 x Motor 1 x Hand Crank Generator1 x Single Pole Double Throw Switch2 x Switch1 x LED Seat2 x Bulb Holder1 x Magnetic Car8 x Wire 1 x Screwdriver1 x Plastic Box
