Talk about it

Have you ever played with magnet toys?

Magnet toys are a fun toy. What magnet toys have we played with?

Communicate with everyone the phenomena observed when playing with magnet toys.

What magnet toys have you seen and what are their shapes? Please tell me.

Although the magnets shown above have different shapes, they all have the same thing. Please look at them carefully and talk about them.

The magnets above are marked with the letters N and S.

S stands for South Pole, N stands for North Pole

Small experimental requirements:

1. During the experiment, use a magnet to slowly approach each material to see what happens. Each experiment should be repeated several times to ensure accuracy.

2. Observe carefully and put together objects that can be attracted by magnets and objects that cannot be attracted by magnets.

3. Experimental equipment must be well protected, handled with care, and used safely.

4. After the experiment is completed, the experimental equipment must be organized.

Analyzing the experimental records, do you now know the characteristics of magnets? What kind of objects can magnets attract?

Note your findings below.

Distinguish the fine points clearly:

Xiao Ming's father went out for something. At this time, an uncle brought a bag of items to sell. He said that they were all iron products. Xiao Ming was dumbfounded. How should we distinguish iron products from non-iron products? Please ask. Help him think of a good way.

Do it

Does each part of the magnet's "body" have the same magnetic force, or which part is greater?

The teacher prepared a bar magnet and some paper clips for the students. How can we use these materials to verify our guesses?

Explore which part of the magnet has the strongest force

Things to note when experimenting:

1. Select several points on the magnet and hang paper clips on each point in turn.

2. Handle with care.

3. Record in time.

4. Communicate the findings in the experiment softly.

5. What are the rules when other students compare the data of each group?

The two ends of a magnet with the strongest magnetic force are the two magnetic poles of the magnet.

The South Pole is represented by the symbol "S" and the North Pole is represented by the symbol "N".

Experiment records

Bar magnets attract more at both ends and less in the middle.

Horseshoe shaped magnet attracts more at both ends and less in the middle

Experimental results: The magnetic force at both ends is large, and the magnetic force in the middle is small.

Based on the experimental research, discuss and communicate: What are the characteristics of magnets that attract objects? Write down your common conclusions below.

Through experiments we found:

1. Magnets have the magnetic ability to attract objects made of ________ materials.

2. The two ends of the magnet have strong magnetic force and the middle magnetic force is small.

3. The two ends or two surfaces with strong magnetic force are the two magnetic poles of the magnet. The magnetic force is strong at the two poles and weak in the middle.
