Why is iron magnetic and copper is not?

In summary, iron is magnetic due to its unpaired electrons in the outermost energy level, while copper is non-magnetic because all of its electrons are paired up. This atomic structure of iron and copper greatly contributes to their magnetic properties. Copper cannot be made magnetic because it does not have unpaired electrons, but it can be temporarily magnetized. Iron is used in magnets instead of copper because it has a higher magnetic susceptibility and can create stronger magnetic fields. Temperature and impurities can also affect the magnetic properties of iron and copper.

1. Why is iron magnetic and copper is not?

Iron is magnetic because it has unpaired electrons in its outermost energy level, which allows it to easily align its magnetic moments. Copper, on the other hand, has all of its electrons paired up, making it non-magnetic.

2. How does the atomic structure of iron and copper contribute to their magnetic properties?

Iron has an atomic structure with 26 electrons, 8 of which are in its outermost energy level. Of these 8 electrons, 2 are unpaired and can easily align their magnetic moments. Copper, on the other hand, has 29 electrons with all of them paired up in its outermost energy level, making it non-magnetic.

3. Can copper be made magnetic?

No, copper cannot be made magnetic as its atomic structure does not allow for unpaired electrons. However, it can be temporarily magnetized by placing it in a strong magnetic field, but it will lose its magnetism once removed from the field.

4. Why is iron used in magnets instead of copper?

Iron is used in magnets because it has a higher magnetic susceptibility compared to copper. This means that iron is easier to magnetize and can create stronger magnetic fields.

5. Are there any other factors that contribute to the magnetic properties of iron and copper?

Yes, temperature and impurities can also affect the magnetic properties of iron and copper. At high temperatures, both metals lose their magnetism. Additionally, impurities can disrupt the alignment of magnetic moments in iron, making it less magnetic.
