Questions and Answers

What is the primary reason for the importance of alternating current discussed in the chapter?

  • It is easier to generate than direct current
  • It is a more cost-effective method for transmitting electricity over long distances (correct)
  • It is safer to use in households
  • It has higher voltage capabilities

    • How does a current carrying loop behave when placed in a magnetic field?

  • It becomes non-conductive
  • It behaves like a magnet and experiences a torque (correct)
  • It loses its magnetic properties
  • It repels the magnetic field

    • What causes a material to exhibit magnetic properties as a whole?

  • Increase in temperature
  • Introduction of an electric charge
  • Exposure to direct current
  • Alignment of many atoms along a magnetic field (correct)
