According to Lenz's law, an induced current in the direction depicted in the picture would be created when: a. An external downward field is created or an external upward field is removed b. An external upward filed is created or an external upward field is removed c. An external downward field is created or an external downward field is removed d. An external upward field is created or an external downward field is removed

answer: i don't know the answer good luck

explanation:

answer would be letter choice (a),   a ball resting on a shelf. would be another example of potential energy   >   stored energy > not moving.

a ball spinning on a finger   >   kinetic energy > moving energy

a ball rolling on the ground   >   kinetic energy   > moving energy

a   ball flying through the air   > kinetic energy   >   moving energy

hope that                                         : )
