He also designed a variety of experiments, such source. It has many advantages like low power consumption, high as the relative movement of the two coils, the changes of magnetic brightness, compact size, light weight, long life span and so on. 1. If the crank can not drive motor rotation, please check if gears are force that can also produce current. In this way, Faraday finally installed correctly. Ask parents for help if nessassary. opened the law of electromagnetic induction. The discovery for 2. If the LED lantern does not light up, please ensure all connections are in Faraday cleared the road to explore the nature of electromagnetics contact, especially the connectors of the two wires. and opened a large number of new ways to generate currents. Q: Why does the LED light produce different colors when moving the crank in different How To Play directions 1. Turn the crank clockwise or counterclockwise, the LED lantern will glow in Q: How is electricity Coil Crank blue and green light. generated from the A: In fact, we use two-color light-emitting diodes, that is, two 2. You can let the light irradiate to different angles by adjust the angle of the Dynamo Lantern different colors of LED are in reverse parallel and packaged in LED lantern base. (DO NOT look at the LED light directly when it is lit up.) Mageneton container. As shown on the right, when the current flows 3. Quickly turn the crank back and forth, the LED light will alternately glow in S N from the left to the right, the upper LED will be lit. On the contrary, blue and green light. the under LED will be lit. This is the secret of two different colors LED Light 4. Fill the plasitc lantern cover with water, screw the LED lantern light in the forward and reverse rotation. components into it (as shown below), connect the plug, and turn the crank, the water will reflect the LED light. A: When a part of the conductors in closed circuits do the movement of cutting magnetic induction line in the magnetic field, Fun Tips: Add confetti or glitter to the water lantern for a light show snow the conductors will produce electric current, which is called lantern. Alternatively, add stickers to the outside to make some CRAZY electromagnetic induction phenomenon. In our Dynamo Lantern, shadows For more tips/tricks, please visit our website at www.odevbot.com the coils are coiled on the central shaft of the motor, with two magnets mounted on the inner wall of the motor casing. When the crank is turned, the central shaft rotates, producing a powerful current, then the LED lantern lights, which is the basis of the generator. Left Right Q: What is the role of gears in the dynamo Fill in with Lantern water Light Reflection A: To drive the motor to turn on the LED light requires a high Water Lantern speed. The hand rotation alone can not reach that speed, so we use the gears to help. Using the large gear drive pinion to rotate, Attention: The voltage generated by this product is very low that will cause no harm to human. we can increase the speed of the pinion. The gear speed is Do not do the same experiment to other lamp light as it may cause damage and serious injuries. increased by the transmission ratio of the gears. The transmission ratio of the gears equal to the ratio of the drive gear speed to the driven gear speed (or inverse ratio of the number of teeth on the drive gear to the number of teeth on the driven gear). Lets learn some The Basic Principle of Gear Rotation fun facts Wow You did a great job Q: Who is the first inventor of hand crank dynamo a. Deceleration b. Acceleration I - Drive gear (pinion) II - Driven gear I - Drive gear II - Driven gear (pinion) A: Michael Faraday was the first inventor of the hand crank dynamo. He was a brilliant scientist, who had Figure a is the deceleration, that is the pinion drives the large gear an outstanding contribution to the electromagnetic to rotate. Figure b is the acceleration, that is the large gear drives field. A lot of physic theories found today have been the pinion to rotate. derived from his research. nd th Michael Faraday (Sept. 22 ,1791-Aug. 25 , 1867) was a famous British self-taught physicist and chemist. Born to a poor blacksmith Q: What is an LED How does it light up family in Newington, Surrey County he had only attended elementary school as his formal education. On October 17th, 1831, Faraday first discovered the phenomenon of electromagnetic A: LED is short for Light-Emitting Diode, with unilateral conductivity, induction. This breakthrough in the field of electric power research as shown below. When the left side of the LED voltage is greater changed human civilization, and his discovery was instrumental in than the right side of the voltage exceeding a certain threshold, it will Maxwell s equations (A set of partial differential equations that, form a positive to negative forward conduction current, than the LED together with the Lorentz force law, form the foundation of classical will be lit. On the contrary, when the LED is not damaged, it will not Designed and Distributed By: electromagnetism, classical optics, and electric circuits). Due to his form a conduction current, and LED will not be lit. Tenergy Corporation contribution to electromagnetism, he was known as theFather of 436 Kato Terrace, Fremont, CA 94539, USA Electricit. Designed and Manufactured By: After nearly 10 years of continuous experiments, Faraday Beijing Today Innovation Technology Co.,Ltd. No.118, Floor 1, Building 1, No.7, North Ritan Road, concluded in 1831 the magnetic force of a current coil can not Chaoyang District, Beijing, PRC cause current in another coil.
