Paramagnetic Substances:
Paramagnetic substances are those that are weakly attracted to magnetic fields. This attraction is due to unpaired electrons in the atoms of the substance.
Resultant Dipole Moment:
- For a substance to be paramagnetic, its atoms must have a resultant dipole moment. This means that the individual atoms have a net magnetic moment due to the presence of unpaired electrons.
- When a paramagnetic substance is placed in an external magnetic field, the magnetic moments of the atoms align with the field, causing the substance to be weakly attracted.
Zero Dipole Moment:
- A substance with a zero dipole moment would not exhibit paramagnetic behavior because there would be no net magnetic moment to interact with an external magnetic field.
Negative Susceptibility:
- Negative susceptibility is a property of diamagnetic materials, not paramagnetic materials. Diamagnetic materials are weakly repelled by magnetic fields, unlike paramagnetic materials which are weakly attracted.
High Relative Permeability:
- While paramagnetic materials do have a higher relative permeability compared to non-magnetic materials, this alone is not a defining characteristic of paramagnetism.
- The key factor is the presence of a resultant dipole moment in the atoms of the substance.
In conclusion, for a substance to exhibit paramagnetic behavior, its atoms must have a resultant dipole moment due to the presence of unpaired electrons. This allows the substance to be weakly attracted to magnetic fields when placed in an external magnetic field.
