Respond to the following: What is a magnetic field? The space around a magnet in which a magnetic force is exerted. Draw the magnetic field lines for the diagram below (copy the magnetic on your warm-up).
Electromagnetism (25 minutes) Start video at 1:14 and end at 19:22 When you are finished with the notes Show me and I will enter your grade. Pick up the handout for motors, generators, and transformers. Read the handout and use the following questions to guide your reading: What type of energy transfer takes place in a motor? What type of energy transfer takes place in generator? What type of energy transfer takes place in a transformer?
Practice With your group, complete the practice problems. When you are finished please show me and I will enter your grade and you can check the key.
