I think the correct answers from the choices listed above are options B and C. A credit card and an access card you scan for entry into a building are most likely to be affected by a magnet. Hope this answers the question. Have a nice day.

Answer;

C.An access card you scan for entry into a building

Explanation;

  • Magnets are materials that have the capability of producing magnetic field. Magnets attract magnetic material such as iron and cobalt while they don't have an effect on non-magnetic materials such as wood and plastic.
  • Access cards are plastic cards with a microchip or a magnetic strip containing an encoded data that is read for an individual to gain entry into a building.
  • Due to the presence of a magnetic strip that is swiped through the mechanism in the door, they may be affected by magnetic field from the magnets.
