Two parallel conductors carrying current in the same direction attract each other, while two parallel beams of electrons moving in the same direction repel each other. Which of the following statements provide part or all of the reason for this? (a) The conductors are electrically neutral. (b) The conductors produce magnetic fields on each other. (c) The electron beams do not produce magnetic fields on each other. (d) The magnetic forces caused by the electron beams on each other are weaker than the electrostatic forces between them.
