Competency #8
Answer and Explanation
Sort the following objects into 3 categories according to their magnetic properties: A bar magnet, nail, wood, copper, horseshoe magnet, paper clip, aluminum soda can, and a nail.
Explain the 3 categories you chose.
Answer:
| Magnets | Magnetic | Non-magnetic |
|---|---|---|
| Bar magnet | Paper clip | Copper |
| Horseshoe magnet | Nail | Aluminum can |
The first category, ‘magnets,' contains objects that are attracted to each other as well as to magnetic materials. The second category, ‘magnetic,' contains objects that are attracted to magnets, but not to each other. The final category, ‘non-magnetic,' contains objects that have no magnetic attraction to any objects.
