A 5 kg magnet exerts a constant force of 3 N on a 0.25 kg magnet. What force will the smaller magnet exert on the larger magnet?

To find the force that the smaller magnet exerts on the larger magnet, we can use Newton's third law of motion, which states that for every action, there is an equal and opposite reaction.

Since the larger magnet exerts a force of 3 N on the smaller magnet, the smaller magnet will exert an equal and opposite force on the larger magnet.

Therefore, the force that the smaller magnet exerts on the larger magnet is also 3 N.
