"The Two Poles of a Magnet" Magnet PPT

Description

"The Two Poles of a Magnet" Magnet PPT

Part 1: Where does a magnet have the strongest magnetic force?

Use a bar magnet to study where the magnet has the strongest magnetic force.

How many parts should the magnet be divided into and measured?

How to measure the magnetic force of each part?

experimental method

1. Divide the magnet into 5 equal parts from left to right.

2. Use different parts of the magnet to attract paper clips.

3. Record the results on the recording paper.

Experimental suggestions

1. Each part is tested separately to avoid affecting the experimental results.

2. The experimental methods should be the same to avoid affecting the experimental results.

3. It can be repeated several times to obtain more accurate results.

PPT of the two poles of the magnet, part 2: Research on the two poles of the magnet

If you hold two unmarked magnets with two hands and bring their poles close to each other, what will happen? How do our hands feel?

When the magnetic poles of two magnets are close to each other, sometimes they will be attracted to each other, and we call them attracting each other; sometimes they will be pushed to both sides, and we call them to repel each other.

Can we accurately tell which two magnetic poles attract each other and which two magnetic poles repel each other when two magnets are close to each other?

Label the two ends of the two magnets A, B, C, and D respectively, and then bring them close to each other.

Use the symbol "→←" to indicate mutual attraction, and use the symbol "←→" to indicate mutual repulsion. Record the results of the experiment.
