Description

"Magnetic Force of Electromagnets (1)" Energy PPT Courseware 3

teaching objectives

Knowledge goal :

Learn more about the properties of magnets through personal practice, and learn about the factors that affect the magnetic properties of electromagnets by exploring the factors that affect the magnetic properties of electromagnets.

Organize and guide students to initially learn to design experiments to enhance the magnetic properties of electromagnets.

Understand the wide range of applications of electromagnets in production and life.

Competency goals:

Based on the experience accumulated by students in production, students' observation and inquiry abilities will be cultivated through activities that explore the factors that affect the magnetic properties of electromagnets.

In the process of exploring the factors that affect the magnetic strength of electromagnets, students' expression, analysis and induction abilities are cultivated.

Emotional attitudes and values:

In the process of exploration, you can boldly imagine and make well-founded hypotheses, and conduct experiments to test hypotheses with a rigorous scientific attitude.

Use the scientific knowledge learned to solve problems, and cultivate the spirit of being willing to cooperate with others in activities

Propose a hypothesis and test it experimentally

Who can guess how the magnetic force of an electromagnet can be changed?

The first method: increasing the number of batteries can change the magnetic force of the electromagnet

The second method: increasing the number of turns of the coil can change the magnetic force of the electromagnet

The third method: increasing the number of battery cells and coil turns can change the magnetic force of the electromagnet

friendly reminder

We can design an experimental plan in table format. The design of the record table can have the following columns:

1. What topic has your group decided to research?

2. What conditions should be controlled unchanged in the experiment? Which conditions need to be changed?

3. What materials are needed for research?

4. Record the experimental results (record the number of pins picked up)

Classroom development. Learning and communication

Through study, do you also know which electromagnets are used in production and life?

Is there anything else you want to invent through learning?

"Magnetic Force of Electromagnets (2)" Energy PPT Download Part One: Review Introduction An electromagnet is a device composed of a coil and an iron core. The magnetic force of the electromagnet is related to the number of coil turns: the greater the number of coil turns, the greater the magnetic force, and the smaller the number of coil turns..
