The potatoes don't provide any energy. That's a common misconception, the energy actually comes from the two electrodes. The potato just acts as a salt bridge and ion supply. You see, when the two different metals are stuck into the potato, one of them releases positive ions into the liquid in the potato more easily than the other.
Generators use magnetic fields to create electrical energy. But the energy is not coming out of the magnets, it is made by burning fuel or nuclear fission. The magnetic fields inside the generators only act as a means to make the energy transformation. The magnetic energy does in no way contribute to the energy output. I have a suspicion that your actual question is if the energy from magnets can be harvested, the answer to that is a resounding no, as the process would deplete the magnet very soon.
