Problem: Given the question: John wanted to charge his electronic gadgets remotely. To that end, he first conducted two experiments, case A and case B. In case A he used conduction, and in case B he used induction. In both cases he used same two objects. Finally, John tried to charge his phone remotely. He called this test as case C. Would the objects be closer to or farther from each other in case B than in case A?
