Unformatted text preview: induces a momentary current in the loop. Which direction will the current flow around the loop? Show with an arrow on the loop. Show your reasoning as in the example. S N Solution: Inside the loop, the magnets B-field points right (toward south) and increases as the magnet gets closer. This change points right. Current flows in the loop to oppose this change, so up in front. initial field later field change in field loop field (opposite) current direction S N S N current flow when turned on...
