"Will the size of magnetism change?" Magnet PPT courseware 2

Review old knowledge

1. The property of magnets that can attract iron is called _______.

2. The strongest magnetic part of the magnet is called _______, and the magnet has _______ magnetic poles. We call the magnetic pole pointing north _______ and the magnetic pole pointing south _______. Two identical magnetic poles are called _______, and two different magnetic poles are called _______.

3. When two magnets are close to each other, the same poles will _______ and the opposite poles will _______.

Kind tips

1. Make a paper clip into a small hook, and hang the other paper clips on the hook one by one.

2. Gently hold the paper clip with your hand while it rotates.

3. Work in groups, one person hangs up, another counts the number, other students observe and write down the number before falling.

4. For the accuracy of the experiment, two operations must be performed.

5. After the experiment is over, organize the experimental equipment. Analyze the data obtained and draw conclusions.

Summary

Through research on ring magnets, we found that when two or more ring magnets are attracted together, the magnetic force will increase.

Think about it:

If two mutually repelling magnets are forcibly combined, will their magnetic force change?

after school activities

There are many shapes and combinations of magnets. Will their magnetic force change when they are together? What's the change?

Students can choose several situations to study outside of class.
