Learn on PengiAmplify Science (California) Grade 8Chapter 1: Modeling Magnetic Force

Lesson 3: Attraction and Repulsion

Key Idea.

Section 1

The Rule of Poles

Key Idea

Every magnet has two distinct ends: a North pole and a South pole. The interaction between magnets is governed by the orientation of these poles.

The fundamental rule is: Opposites attract, and likes repel.

Section 2

Predicting Interactions

Key Idea

Understanding pole orientation allows for the prediction of movement.

If a system requires a launching (pushing) force, the magnets must be arranged with like poles facing each other to create repulsion.
