Question

If you use the property of magnetic  attraction to classify objects, what would  be the result for Wooden and Iron tables?

Accepted Answer

Option 3 is the correct answer because when using the property of magnetic attraction to classify objects, wooden and iron tables would belong to different groups. This is due to the inherent properties of the materials from which they are made.

1. **Explanation for Option 3:**
   - **Iron Table:** Iron is a ferromagnetic material, meaning it is strongly attracted to magnets. This property is due to the alignment of its atomic magnetic moments, which can be easily influenced by an external magnetic field.
   - **Wooden Table:** Wood is a non-magnetic material. It does not have the atomic structure that allows for magnetic attraction. Therefore, a wooden table would not be attracted to a magnet.
   - Since the iron table is attracted to magnets and the wooden table is not, they would be classified into different groups based on their magnetic properties.

2. **Explanation for why other options are incorrect:**
   - **Option 1:** This option suggests that both wooden and iron tables would belong to the same group. This is incorrect because they have different magnetic properties. Iron is magnetic, while wood is not, so they cannot be grouped together based on magnetic attraction.
   - **Option 2:** This option states that the wooden table would be attracted, while the iron table would not. This is incorrect because it contradicts the fundamental properties of the materials. Iron is magnetic and would be attracted, whereas wood is non-magnetic and would not be attracted.
   - **Option 4:** This option claims that both wooden and iron tables would be repelled by the magnet. This is incorrect because iron, being a ferromagnetic material, is attracted to magnets, not repelled. Wood, being non-magnetic, is neither attracted nor repelled.

In conclusion, Option 3 is correct because it accurately reflects the different magnetic properties of wood and iron, leading to their classification into different groups based on magnetic attraction.
