Discussion week: magnetic fields, magnetic forces, and induction.
Scientists often make predictions. To make a prediction, scientists use the best possible and most available prior knowledge that they have at the time. Sometimes the predictions are correct, and sometimes they are not. In this discussion, you will practice making predictions based on what you see when you quickly skim through a portion of the textbook.
Skim Ch. 22, “Magnetism,” of College Physics in this week’s Learning Activities folder. (You do not need to read this chapter in full to answer the discussion questions. You will read the chapter later this week as you complete your activities and assignments.) After you have skimmed the chapter, select one section (e.g., Section 22.2: Ferromagnets and Electromagnets). For additional background, you may explore topics related to Magnetism Physics and Electromagnetism.
Respond to the following:
Identify the title of the section you selected.
Predict how the information in the section you selected might add to your understanding of the learning goal for this week: Define and use the electromagnetic spectrum to explain natural phenomena.
Predict how information from the section you selected might help you in your future career. Also, discuss how not knowing the information might hinder your future career.
Pick 1 image, figure, or graph from the section that stands out to you and briefly describe it. Provide the figure number, a figure description, and the page number of the image (e.g., Figure 22.7, an unmagnetized piece of iron placed between two magnets becomes magnetized through heating and tapping or heating and cooling, p. 957). Discuss what made the image interesting to you and why you selected it.
Students may also find concepts related to Electromagnetic Induction useful when exploring magnetic fields and their practical applications.
