Preface:

In today's increasingly emphasis on children's education, scientific enlightenment education has gradually become an important topic in the field of education that is pursued and explored. More and more teachers and parents are beginning to pay attention to cultivating children from an early age.
Scientific literacy from an early age helps children to develop good character and behavioral habits from the start. Parent-child interactive crafts can improve the quality of parent-child companionship, enhance the relationship between parents and children, and enrich the time we spend with our children.
Without mobile phones, iPads, or televisions, there is only joy, interaction, and communication. This can cultivate the ability of children to solve problems on their own. When they encounter problems, they should first see and experience the solution themselves, because parents should not solve the problem for them.
Mom teacher solves problems in the process of making crafts. It can develop children's imagination. In children's world, cars can fly in the sky, and the sun can be green... Play with your hands.
DIY crafts can cultivate children's ability to use different tools, allowing their little hands to get a full range of movement. Brushes, paints, scissors, hot glue guns, glue..., they dare to use any tool.
Trying, to a certain extent, develops different skills. Improving children's self-confidence in the process of handcraft, we try all possibilities together, experience many failures, but we always succeed, to a certain extent.
The confidence of the child has been enhanced. When the child is exploring various tools and crafts, he is very focused, and if there is no external disturbance, he can continue to explore.
。

The purpose of the experiment is to enhance intelligence, promote interaction, and practice skills.

Principle Application: The principle of electromagnetic induction, which is that a coil generates an induced electric potential in a rotating magnetic field. The basic components of a generator include a stator and a rotor. The stator is usually a permanent magnet.
A coil, when driven by an external force, rotates within a magnetic field.

A current-carrying conductor moving through a magnetic field generates an electromagnetic field.

If the internal coil is connected to the external circuit through a brush.

Form a closed loop then
In this circuit

Current is formed.

Experimental Cognition: A hand-cranked generator produces mechanical energy by converting the work done by hand-cranking into rotation, which can then be used to generate electricity.

Knowledge Expansion: A generator is a device that converts other forms of energy into electrical power, dating back to the era of the Second Industrial Revolution.

Knowledge Extension: There are many types of generators, and their working principles are all based on the changes in electromagnetic fields to produce electricity. Since the working principles of generators differ, they are divided into direct current generators and asynchronous generators.
Machine and synchronous generator.
