I’m working on a science discussion question and need a sample draft to help me learn.
Discussion: Applications of Magnetism
Complete the readings and watch the videos in this topic. Then answer the following questions:
1. In your own words, what are three things you learned about magnetism and/or electromagnetism from the readings and videos? What did you find particularly interesting or surprising about what you read/watched?
2. Select one idea/concept from this topic that was unfamiliar to you prior to this lesson. How would you explain this concept to someone who is new to the physical sciences?
3. Identify three applications of magnets or electromagnets in everyday life. How are these magnets/electromagnets used, and why are they important?
Respond in ~300-400 words. Reply to one other post.
