Preface:

In today's society, where children's education is increasingly valued, scientific enlightenment education has gradually become an important topic in the field of education, which is pursued and explored. More and more teachers and parents are beginning to pay attention to cultivating children's scientific literacy from an early age, so that children can develop good personalities and behavioral habits from the beginning. Parent-child interactive crafts can improve the quality of parent-child companionship, improve the relationship between parents and children, and we spend time with our children, without mobile phones, iPads, or televisions, only joy, interaction, and communication. It can cultivate the ability of children to solve problems by themselves. When children encounter problems, they should first see and experience the solution themselves, because parents and teachers solve problems in the process of doing crafts. It can develop children's imagination. In children's world, cars can fly in the sky, and the sun can be green. Playing with DIY crafts can cultivate children's practical ability by using different tools, which fully exercises children's little hands. Brushes, paints, scissors, hot-melt guns, glue"Children are brave to try any tools and to some extent, they are developing different skills. Improving children's self-confidence in the process of handcrafts, we try everything possible together, experience many failures, but we always succeed, which to some extent enhances their self-confidence. Cultivating children's concentration when children explore various tools and handcrafts, they are very focused, and if there is no external disturbance, they can continue to explore.

The purpose of the experiment: To enable children to learn more about scientific knowledge and their own ability to practice by means of game entertainment.

Principle of Application: The working principle of a hand-cranked generator is to cut magnetic lines of force manually to generate electricity.

Experimental Cognition: The generation process of an alternating generator is that a closed coil rotates in a magnetic field, utilizing the electromagnetic induction phenomenon to produce induced current, so its generation principle is electromagnetic induction.

Knowledge Expansion: In the process of generating electricity, a hand-cranked generator converts mechanical energy into electrical energy. When a coil rotates within a magnetic field, it generates an induced electric potential. The basic components of a typical hand-cranked generator are the stator and the rotor. The stator is usually a permanent magnet, while the rotor is a coil. When the coil rotates within the magnetic field, it cuts the magnetic lines of force to generate an induced electric potential. If the internal coil is connected to an external circuit through a brush, and forms a closed circuit, then an electric current is formed in this circuit!

Knowledge Extension: A generator is composed of stator, rotor, end cover, base, and bearings, among other components. The stator is made up of the base, stator core, winding, and other components that fix these parts. The rotor can rotate within the stator, cutting magnetic lines of force, thereby generating induced voltage to generate electricity.

Safety Warning:

All the accessories in this product are specially designed for student experiments. Please use them under the supervision of teachers and parents to ensure safety! Do not consume any of the products! They are not suitable for children under three years of age. Do not approach fire sources. Before assembling any batteries, please check if the circuit is clear, all parts of the circuit are complete, and all contacts are good. The + on the battery is the positive pole, and - is the negative pole. Be careful during the assembly process, and if glue is used, do not get it in your eyes or on your skin.
