  4. 8. the area around a magnet, magnetic object, or an electric charge in which magnetic force is exerted
  5. 10. force a force that affects subatomic particles and other objects that contain electrical charge
  6. 11. refers to the opposition that a material or component offers to the flow of electrical current
