This document provides an introduction to magnetism for a 5th grade student. It begins by asking why they are learning about magnetism after just studying electricity. It then reviews what is already known about magnets, including that opposites attract and the earth acts as a magnet with magnetic north different from geographic north. Finally, it introduces the concept of magnetic lines of force and compares them to the force of gravity.

2. WHY MAGNETISM?
Why are we learning about magnetism? I thought we were learning about electricity?

3. MAGNETS
WHAT DO WE ALREADY KNOW?

4. MAGNETS
Magnets attract/repel each other

5. MAGNETS
Magnets attract/repel each other
• Opposites attract so the north pole of a magnet
attracts the south pole of another magnet

6. MAGNETS
Magnets attract/repel each other
• Opposites attract so the north pole of a magnet
attracts the south pole of another magnet
The Earth acts like a magnet

7. MAGNETS
Magnets attract/repel each other
• Opposites attract so the north pole of a magnet
attracts the south pole of another magnet
The Earth acts like a magnet
• Magnetic north is different than the Geographic
North Pole

8. WHAT ARE MAGNETIC LINES OF FORCE?
Lets compare it to force of gravity
