Learning Goals

Name the two poles of a magnet and state the rule of polarity.
Identify which everyday materials are magnetic.
Recall that magnetic force gets weaker as distance increases.

Warm Up

Match each word to its meaning

Draw a line connecting each word on the left to its correct description on the right. Or write the matching letter next to each word.

Word	Your answer	Description
Pole		A. To push apart, what like poles do to each other
Attract		B. One of the two ends of a magnet, where the force is strongest
Repel		C. A material that is pulled toward a magnet, such as iron or steel
Magnetic material		D. To pull together, what unlike poles do to each other
Compass		E. A tiny magnet on a free pivot that lines up with Earth's magnetic field

Your Turn

Fill the gap

Choose the correct word from the word bank to complete each sentence. Two words will not be used.

north south repel attract iron weaker plastic stronger

Every magnet has two poles, a pole and a south pole. Like poles each other, which means they push apart. Unlike poles each other, which means they pull together. A magnetic material such as is attracted to a magnet, but wood and copper are not. As an object moves further from a magnet, the magnetic force gets . A material like is not magnetic, so a magnet does not attract it.

Show What You Know

1. A student says: "When two north poles are brought together, they pull toward each other." Is the student correct? Explain your answer using the words "like poles".
