Frederick sets paper clips out on a table. He then takes a magnet, places it directly beneath the paper clips under the table, and moves the magnet. He finds that the paper clips move with the magnet. Why does this happen?
Magnetic force is a repellant force
Magnetic forces act on wood, like in the table
The paper clips are feeling the gravitational force of the magnet
Magnetic forces act at a distance, even between objects
