Lesson⭐ 30 XP⚡ Spark LabMagnets: Attract and Repel (Part 3)
Motion and Forces.
🎯 Your mission
Learn the rule. Then catch nature using it.
⚡ The twist
The opposite of what you expect is often what happens.
Mind = Blown
🎢 You feel weightless on a roller coaster because you and the seat are falling at the same speed.
Make a hypothesis first
Predict: what happens if you double the force?
What You'll Learn
Magnets have north and south poles. Opposite poles attract and like poles repel. The magnetic field is strongest at the poles and gets weaker with distance.
Key Words
- force
- Newton
Steps
Read about Motion and Forces and write down three key facts.
Build an electromagnet by wrapping insulated wire around a nail and connecting it to a battery. Test how many paper clips it can pick up. Try adding more wire coils.
Look for patterns in your observations.
Make a graph or chart showing your results.
