Good metal conductors

  1. Name 3 good metal conductors listed from lowest to highest resistance. Give an application example for one of these materials.
  2. Why is it very difficult to measure the hot resistance of a lightbulb filament with an ohmmeter?
  3. Define the following acronyms: SPDT, DPST, DPDT, NO, NC.
  4. Why does ionization occur more readily in liquids and gases in comparison to solids?
  5. What is resistance wire? Give an application example for its use that is not a toaster or space heater.

Chapter 13 in (Magnetism) and answer the following questions:

  1. What is the Maxwell a unit of?
  2. What is the name for a nonmetallic material that has the ferromagnetic properties of iron?
  3. Name two magnetic materials and three nonmagnetic materials.
  4. What is a toroid?
  5. Explain what the units of gauss measure. Do the same for the units of tesla.

Watch the video below. After you have done so, submit an idea for an application that would be uniquely suited for the type of magnet technology covered in this video. Explain the idea to me in 200 words. If a sketch would be helpful, please attach one. A sketch upload can be substituted for 100 words in the text requirement.
