Web液態氧涓流被磁場偏轉，顯示出其順磁性。. 順磁性 （Paramagnetism）指的是一種材料的磁性狀態。. 有些材料可以受到外部磁場的影響，產生跟外部磁場同樣方向的 磁化向量 的 … Paramagnetism is a form of magnetism whereby some materials are weakly attracted by an externally applied magnetic field, and form internal, induced magnetic fields in the direction of the applied magnetic field. In contrast with this behavior, diamagnetic materials are repelled by magnetic fields … See more Constituent atoms or molecules of paramagnetic materials have permanent magnetic moments (dipoles), even in the absence of an applied field. The permanent moment generally is due to the spin of unpaired … See more Materials that are called "paramagnets" are most often those that exhibit, at least over an appreciable temperature range, magnetic susceptibilities that adhere to the Curie or Curie–Weiss laws. In principle any system that contains atoms, ions, or molecules with … See more • Media related to Paramagnetism at Wikimedia Commons • Magnetism: Models and Mechanisms in E. Pavarini, E.
