Answer the following question given this paragraph: Since eddy currents and magnetic damping occur only in conductors, recycling centers can use magnets to separate metals from other materials. Trash is dumped in batches down a ramp, beneath which lies a powerful magnet. Conductors in the trash are slowed by magnetic damping while nonmetals in the trash move on, separating from the metals. (See Figure 23.17. ) This works for all metals, not just ferromagnetic ones. A magnet can separate out the ferromagnetic materials alone by acting on stationary trash. Q: Since eddy currents and magnetic damping occur only in conductors, recycling centers can use these to separate metals from other materials? Choices: - particles - cranes - alloys - magnets A:
A:
magnets
