1. Due to friction with the Earth's atmosphere, a large static electric charge could build up on a plummeting asteroid fragment. Would you expect the fragment to generate a electric field in this situation? Explain why or why not.
2. Would you expect the plummeting fragment from the previous question to generate a magnetic field? Explain why or why not.
3. Would you expect the plummeting fragment from the previous question to have any effect on nearby electric power lines? Explain why or why not.
