Question

unit exam-gravitational/electrostatic forces
in what direction should the red point of the compass be pointing?
down left
up right

Explanation:

The refrigerator has a magnetic field (from the magnet or magnetic door seal). A compass needle (magnetic dipole) aligns with magnetic field lines. The magnetic field from the refrigerator's magnet (assuming the red part is a north - seeking pole) will be attracted or repelled. If the refrigerator's magnet has a south pole near the compass, the north - seeking (red) part of the compass will be attracted towards the refrigerator, which is to the left? Wait, no—wait, the refrigerator's magnet: if the red on the fridge is a magnet, say the fridge has a north pole? Wait, no, let's think about magnetic attraction. Opposite poles attract. If the fridge's magnet (the red part) is a south pole, the compass's north (red) will be attracted to it, so the compass's red point will point towards the fridge, which is to the left? Wait, the options are Down, Left, Up, Right. Wait, maybe the fridge has a magnetic field that makes the compass point left? Wait, no, maybe I got it wrong. Wait, the refrigerator's door seal or magnet: when a compass is near a magnet, the compass needle aligns with the magnetic field. If the fridge's magnet is on the right - hand side (from the compass's perspective), no—wait, the diagram: the fridge is on the left, compass on the right. The fridge has a red magnet (maybe north pole). The compass's red is north. So like poles repel, so the compass's red would point away from the fridge, which is to the right? No, that's confusing. Wait, maybe the correct answer is Left. Wait, no, let's recall: in a magnet, the magnetic field lines go from north to south. If the fridge's magnet is a north pole, the magnetic field lines go out from it. The compass's north (red) will point along the magnetic field lines. So if the fridge is on the left, and the magnet on the fridge is a north pole, the magnetic field lines from the fridge's north pole will go towards the right (away from the fridge's north). Wait, no, north pole of a magnet has field lines going out, so the compass's north (red) will point in the direction of the field. So if the fridge's magnet is north, the field at the compass is towards the right? No, that would make the compass's red point right. But maybe the fridge's magnet is south. Then field lines go into the south pole, so the compass's north (red) points towards the fridge (left). So the correct answer is Left.

Answer:

B. Left
