Question
A magnet is removed from a refrigerator door and placed on a table. How will the potential energy of the system change in this process? Select the TWO correct answers.(2 points)
Responses
Since the magnet was attached to the refrigerator the magnetic field is in the direction that pulls the magnet to the refrigerator.
Since the magnet was attached to the refrigerator the magnetic field is in the direction that pulls the magnet to the refrigerator.
When the magnet is removed and moved away, it moved in the opposite direction of the magnetic field and so its potential energy increases.
When the magnet is removed and moved away, it moved in the opposite direction of the magnetic field and so its potential energy increases.
Since the magnet was attached to the refrigerator the magnetic field is in the opposite direction that pulls the magnet to the refrigerator.
When the magnet is removed and moved away, it moved in the opposite direction of the magnetic field and so its potential energy decreases

The correct responses regarding the change in potential energy of the system when the magnet is removed from the refrigerator door and placed on the table are:
1. **When the magnet is removed and moved away, it moved in the opposite direction of the magnetic field and so its potential energy increases.**
2. **Since the magnet was attached to the refrigerator the magnetic field is in the direction that pulls the magnet to the refrigerator.**
When the magnet is detached from the refrigerator, it is no longer in the magnetic field that was pulling it towards the refrigerator. Moving the magnet away from the refrigerator increases its potential energy in the magnetic field, as the position of the magnet is less favorable (higher potential) compared to being attached to the refrigerator.
