Description
"Will the size of magnetism change?" Magnet PPT courseware 3
How strong is the magnetic force of a round magnet?
Can we change the magnitude of magnetism?
Our guess:
When two or more magnets are drawn together, the magnetic force increases.
1. The number may be doubled.
2. The number may gradually decrease.
3. The number may gradually increase.
4. The possible quantity will not change.
Experimental requirements:
1. Guess first, then experiment.
2. When hanging paper clips, be careful, handle them gently and count them carefully.
3. Communicate and discuss softly.
Team analysis data:
(1) Observing the experimental data, what is our conclusion?
(2) Is our previous guess correct? Does the number of paper clips increase exponentially or gradually decrease?
Our conclusion:
When two or more magnets are drawn together, the magnetic force increases.
If two magnets that repel each other are brought together, how will the magnitude of the magnetic force change?
There are many shapes and combinations of magnets. Will their magnetic force change when they are together?
