Which of the following best states the rule that fixes the direction of the current induced in a closed circuit when the magnetic flux linked with it changes?
(a) The induced current produces a magnetic field that opposes the original magnetic field causing it.
(b) The induced current flows so as to oppose the change in magnetic flux producing it.
(c) The induced current flows in the same direction as the change in magnetic flux producing it.
(d) The induced current always establishes a magnetic field parallel to the applied field.
