Exploring the Exciting World of Magnets!

What fundamental force are the students observing when experimenting with magnets?

A. electromagnetic B. gravitational C. strong nuclear D. weak nuclear

Answer:

B. electromagnetic

When two students experiment with magnets, they are observing the electromagnetic force at work. This fundamental force is responsible for the interaction between electrically charged particles, such as the poles of the magnets in this experiment.

When the students first try to put the magnets together and they repel each other, it demonstrates the like poles of the magnets pushing away due to the electromagnetic force between them. However, when one student flips over her magnet and the magnets suddenly snap together, it shows the opposite poles attracting each other because of the electromagnetic force.

The electromagnetic force is one of the four fundamental forces in nature, along with gravity, the strong nuclear force, and the weak nuclear force. In this case, the students' observation of the magnets attracting and repelling each other is a clear example of the electromagnetic force in action.
