Question

magnets attract certain materials. a material that is attracted to a magnet is considered magnetic. some metals, such as iron and nickel, are magnetic. other metals, such as copper and aluminum, are nonmagnetic. most nonmetals are also nonmagnetic. when an object is attracted to a magnet, it experiences a magnetic force. magnetic forces can act at a distance. in fact, some large magnets can attract magnetic objects from several feet away. a large magnet on a crane is used to attract scrap metal from a distance. a magnet is held above some magnetic steel paper clips. complete the sentences to describe what can happen. the magnet can make the paper clips move __ them. the paper clips will __ the magnet. b without touching only if it touches

Explanation:

The problem is about magnetic forces and how magnets interact with magnetic materials. From the text, we know magnetic forces can act at a distance (e.g., large magnets attracting scrap metal from feet away). So for the paper clips (magnetic), the magnet can move them without touching (since magnetic force acts at a distance), and the paper clips will be attracted to the magnet. So the first blank should be "without touching" and the second blank (implied by context, like "be attracted to") but focusing on the options given, the first dropdown (move ____ them) should be "without touching" as magnetic force acts at a distance.

Answer:

For the first blank (The magnet can make the paper clips move __ them): "without touching" (as magnetic forces act at a distance, so no contact needed). For the second blank (The paper clips will __ the magnet): "be attracted to" (since they are magnetic and magnets attract magnetic materials). But based on the options shown (the dropdown with "without touching" and "only if it touches"), the correct option for the first blank's dropdown is "without touching".
