Definition

1. Noun:
   • A property of certain materials: "Paramagnetism" refers to the physical phenomenon where specific materials become weakly magnetized when placed in an external magnetic field. This induced magnetization aligns with the direction of the applied field and disappears when the external field is removed.

Usage Examples

• Noun:
  • The scientist explained the principle of paramagnetism using a sample of aluminum.
  • Oxygen exhibits paramagnetism, which is a key characteristic for its detection in certain experiments.
  • Unlike ferromagnetism, paramagnetism is a much weaker and temporary form of magnetism.

Advanced Usage

• "Temperature-dependent paramagnetism": In many paramagnetic materials, the strength of the magnetic susceptibility is inversely proportional to the absolute temperature, as described by the Curie law.

  • The team studied the temperature-dependent paramagnetism of the rare-earth compound.

• "Paul paramagnetism": A specific type of paramagnetism associated with the magnetic moments of conduction electrons in metals.

  • The observed behavior was attributed to Pauli paramagnetism rather than Curie paramagnetism.

Variants and Related Words

• Paramagnetic (adj): Describing a material that exhibits paramagnetism.

  • Aluminum is a paramagnetic material.

• Diamagnetism (n): A weak form of magnetism where a material creates an induced magnetic field in opposition to an externally applied magnetic field.

  • Bismuth is known for its strong diamagnetism.

• Ferromagnetism (n): A strong, permanent form of magnetism exhibited by materials like iron.

Synonyms

• Magnetic susceptibility (in a specific context): While not a perfect synonym, it is the quantitative measure of the extent to which a material can be magnetized, which is positive for paramagnetic materials.

Related Scientific Terms

• Curie's Law: A law describing the magnetic susceptibility of a paramagnetic material in relation to temperature.
• Magnetic moment: The magnetic strength and orientation of an object that produces a magnetic field, which is a key concept in understanding paramagnetism.
