CFA: Magnetic Fields (Chap. 1)

What is the unit question for magnetic fields? How do magnets work? What happened to the launcher? Why do magnets move objects in different ways? What causes attraction and repulsion? Vocabulary Select the term that matches the definition. Vocabulary Word Definition attract to pull an object toward one another magnetic pole one of the two opposite ends of a magnet field lines a line that connects opposite magnetic poles and represents strength of a field repel to push objects away from each other refute to provide evidence that goes against a claim model an object or diagram that helps us understand something by making it simpler or easier to see magnetic field the space around a magnet in which magnetic forces can act on objects Fill in the blank to complete the key concepts.WORD BANK: poles, different, opposite, attract, distance, repelling, pattern, core Key Concepts1. A magnetic force can attract or repel an object at a distance. 2. In a system of magnets, there is a repelling force between like poles and an attracting force between opposite poles. 3. The pattern of magnetic field lines around attracting magnets is different from the pattern of magnetic field lines around repelling magnets. 4. Earth acts as a large magnet with the poles found deep inside, near its core. Using the image above, which model represents magnetic attraction? Model A Model B Using the image above, which model represents magnetic repulsion? Model A Model B Which one of these claims can be refuted based upon evidence provided to us this week? Claim 1 Claim 2 Claim 3
