SUMMARY

Paramagnetic substances exhibit attraction to magnetic fields when placed near the poles of a bar magnet. This phenomenon occurs because the external magnetic field induces a net average magnetic dipole moment in the paramagnetic material, resulting from thermal averaging of unpaired atomic spins. The stronger the external magnetic field, the greater the resultant force experienced by the paramagnetic substance.

PREREQUISITES
  • Understanding of magnetic dipole moments
  • Familiarity with atomic spin concepts
  • Knowledge of external magnetic fields
  • Basic principles of magnetism
NEXT STEPS
  • Research the principles of magnetic dipole moments in detail
  • Explore the effects of temperature on paramagnetic materials
  • Learn about the differences between paramagnetic and ferromagnetic substances
  • Investigate applications of paramagnetic materials in technology
USEFUL FOR

Students of physics, materials scientists, and professionals in fields related to magnetism and magnetic materials will benefit from this discussion.

When a para magnetic substance is brought near a north pole or a south pole of a bar magnet it
experiences attraction. How?Hint : when you put the para magnetic substance in external magnetic field it magnetize. So it experiences the resultant force towards the stronger magnetic field.

Paramagnets in external magnetic fields acquire a net average magnetic dipole moment due to the thermal averaging over the unpaired spins of the atoms in the magnet coupled to the external field.
