Paramagnetism
Paramagnetism (/ˌpærəˈmæɡnɪtɪzəm/) is a form of magnetism whereby certain materials are attracted by an externally applied magnetic field, and form internal, induced magnetic fields in the direction of the applied magnetic field.
Etymology
The term "paramagnetism" is derived from the Greek words "para", meaning "beside" or "near", and "magnetism", from the Greek "magnētis lithos", meaning "magnet stone".
Related Terms
- Diamagnetism: A phenomenon whereby a material becomes a magnet in the presence of a magnetic field.
- Ferromagnetism: The basic mechanism by which certain materials (such as iron) form permanent magnets, or are attracted to magnets.
- Antiferromagnetism: A phenomenon in which the magnetic moments of atoms or ions in a material align in a regular pattern with neighboring spins pointing in opposite directions.
- Ferrimagnetism: A type of magnetism that is exhibited by ferrites and magnetic garnets. The magnetic moments of the atoms or ions align in a parallel direction, resulting in a net magnetic moment.
- Superparamagnetism: A form of magnetism which appears in small ferromagnetic or ferrimagnetic nanoparticles.
