A class about invisible forces in which students learn to make an electric motor is a educational event in which students learn about the principles of electricity and magnetism, and how these forces can be used to create and control motion. In this class, students may:

• Learn about the basic principles of electricity and magnetism: Students may learn about the fundamental concepts and principles of electricity and magnetism, such as electric charges, currents, fields, and forces. They may also learn about the various ways in which these forces can be generated, measured, and manipulated.

• Learn about the principles of electric motors: Students may learn about how electric motors work, and how they are able to convert electrical energy into mechanical energy. They may learn about the different components and systems that make up an electric motor, and how these components interact to produce motion.

• Make their own electric motor: Students may have the opportunity to make their own electric motor using a variety of materials and tools. They may use a variety of techniques to assemble the motor, and to connect it to a power source and a load.

• Test and optimize the performance of their electric motor: Students may use a variety of sensors and measuring tools to test and optimize the performance of their electric motor. They may experiment with different configurations and materials, and use the data and insights they gather to improve the performance of their motor.

Overall, a class about invisible forces in which students learn to make an electric motor can be a valuable educational experience that helps students learn about the principles of electricity and magnetism, and how these forces can be used to create and control motion. It can also be a fun and engaging way for students to develop critical thinking and problem-solving skills.
