Paramagnetism in Materials Explained
Paramagnetism is a type of magnetism where materials are weakly attracted by an external magnetic field. This happens because the material has unpaired electrons, which create tiny magnetic fields that align with the applied field.
Identifying Paramagnetic Material Options
Let's examine the magnetic properties of each option:
- Copper (Cu): Copper is diamagnetic. It is weakly repelled by magnetic fields.
- Iron (Fe): Iron is ferromagnetic. It is very strongly attracted to magnetic fields. Ferromagnetism is a stronger effect than paramagnetism.
- Titanium (Ti): Titanium is paramagnetic. It is weakly attracted to magnetic fields due to unpaired electrons.
- Silver (Ag): Silver is also diamagnetic. It is weakly repelled by magnetic fields.
Conclusion on Paramagnetism
Out of the given choices, only Titanium exhibits paramagnetism, meaning it is weakly attracted by a magnetic field.
