Answer:
The potential energy increase.
Explanation:
Potential energy is the energy stored within a physical system. Energy is the ability to do work or cause movement. A free system acts in the way that minimizes the potential energy, so when you pull a magnet off a refrigerator door you are increasing the potential energy of the system because now if you allow the magnet to move freely, it will snap the door to minimize PE.
The potential energy is the energy of the system at rest. The pulling of the magnet off the refrigerator increases the potential energy.
How potential energy changes in a magnet?
The magnet has two poles attracting each other. When the poles are close to each other they influence the orientations, and resulted in the movement thereby the kinetic energy increase.
The movement of the poles apart decreases the force of influence with the magnet poles and increases the potential energy.
Thus, on moving the magnet off the refrigerator, the orientation changes will be stopped leading to stationary phase, and an increase in the potential energy.
