Juanita sticks a nail to the end of a bar magnet. She then sticks a second nail to the first, then another to that one, and so on. When she gets to the seventh nail, it falls off the sixth nail. Which statement best describes the forces acting on the seventh nail? The force of magnetism is equal to the force of gravity. The force of gravity is stronger than the force of magnetism. The force of magnetism is stronger than the force of gravity.

Answer - The force of gravity is stronger than the force of magnetism.

The attractive force of magnetism is the force that keeps the nails joined to one another and to the end of a bar magnet while the force of gravity is the force acting to pull the nails to the ground. If when Juanita sticks the seventh nail, it falls off the sixth nail, it means that the force of gravity acting on the seventh nail is stronger than the force of magnetism acting on it.
