Use evidence and scientific reasoning to explain why the reading on the balance increased as Magnet 2 was lowered towards Magnet 1. Remember that Magnet 1's North pole was facing upwards while resting on the balance. In your response, be sure to describe the magnetic field interactions and the orientation of the magnetic poles for each magnet.
