Question

in a computer simulation, jose moves a magnet (magnet 1) closer to another magnet (magnet 2) that cannot move. which statement accurately describes the change in potential energy? the potential energy increases because magnet 1 moves against the magnetic force. the potential energy decreases because magnet 1 moves in the same direction as the magnetic force. the potential energy decreases because magnet 1 moves against the magnetic force. the potential energy does not change because the magnets in the system do not change.

Explanation:

To solve this, we analyze magnetic potential energy: when a magnet moves against the magnetic force (e.g., like poles repelling, moving a north pole toward another north pole), work is done on the system, increasing potential energy. Let's evaluate each option:

• Option 1: If Magnet 1 moves against the magnetic force (e.g., repulsion), work is done, so potential energy increases. This matches the physics of magnetic potential energy (work done against the force increases PE).
• Option 2: If it moved in the same direction as the magnetic force (attraction), PE would decrease, but the diagram (implied like - poles or same poles) suggests repulsion, so this is incorrect.
• Option 3: Contradicts the relationship (moving against force increases, not decreases, PE).
• Option 4: Magnetic potential energy depends on position relative to the field, so moving them changes PE. Thus, this is incorrect.

Answer:

The potential energy increases because Magnet 1 moves against the magnetic force. (The first option)
