Word
pinning
Phoneticspin·ning
US/ˈpɪnɪŋ/
UK/pˈɪnɪŋ/
Definition
n. the way a particle's movement is stopped or held in place by a defect in a material. This is very important in physics for making strong magnets work correctly.
n. the restriction of movement of magnetic flux lines or dislocations within a material due to structural defects or impurities. This mechanism is essential for maintaining high current densities in superconductors.
Examples
“Flux pinning allows the magnet to float above the superconductor.”
“The researchers studied how chemical impurities affect the pinning of magnetic vortices in thin films.”
“Effective pinning of magnetic flux lines is a prerequisite for the practical application of high-temperature superconductors in power transmission and medical imaging devices.”
Examples
simple
“Flux pinning allows the magnet to float above the superconductor.”
contextual
“The researchers studied how chemical impurities affect the pinning of magnetic vortices in thin films.”
complex
“Effective pinning of magnetic flux lines is a prerequisite for the practical application of high-temperature superconductors in power transmission and medical imaging devices.”
Usage
Often appears in the compound phrase 'flux pinning' within condensed matter physics.
Real-World Examples
“Tried CPR but could not resuscitate, with the autopsy pinning his death on cardiac arrest.” “Scientists can illuminate how bacteria and archaea emerged by comparing when their ancestors evolved certain traits and pinning down which of those traits might have been inherited from LUCA.” Domain
