First, we verified that magnet movement would induce a current. Each time the magnet moved near the wire loop, whether it was moving forward or in reverse, a current registered. When the magnet was st: 0; Under normal magnet polarity, whenever the magnet was moving toward the loop, the induced current had a value, and a value if the magnet was moving in reverse. Under reversed polarity, we found the re: negative; Under normal magnet polarity, whenever the magnet was moving toward the loop, the induced current had a value, and a value if the magnet was moving in reverse. Under reversed polarity, we found the re: positive; Under normal magnet polarity, whenever the magnet was moving toward the loop, the induced current had a value, and a value if the magnet was moving in reverse. Under reversed polarity, we found the re: opposite

Question 9

In situation A, a bar magnet moves toward a stationary coil at a constant speed, and the maximum current is recorded. If the magnet moves again toward the coil in situation B at the same speed, from the same direction, what would explain the different current reading?
