During induction, a positively charged rod is brought near to but not touching the electroscope. the presence of the charged object above the plate of the electroscope induces charges to move down into the gold leaves, giving the electroscope an overall positive charge. the positive leaves repel. the same process occurs when the north poles of two magnets are brought close together: the two poles push away from each other. both illustrate the principle that a) like charges or poles repel. b) induction produces magnetism. c) electricity induces magnetism. d) opposite charges or poles repel.
