The true answers that best describe magnetic force are:

  1. Magnetic force is generated by moving electrical charges or aligned atoms.
  2. Magnetic force can act at a distance to attract objects to each other.

To clarify:

  • Magnetic force is indeed generated by moving electric charges (such as in a current-carrying wire) or by certain arrangements of atoms (as in magnets).
  • It can act at a distance, meaning that magnetic forces can attract or repel objects without direct contact.
  • However, it is not accurate to classify magnetic force as a contact force, as it does not require physical touch to exert its influence.
