paramagnetism

/ păr′ə-măgnĭ-tĭz′əm /

  1. The property of being weakly attracted to either pole of a magnet. Paramagnetic materials, such as aluminum and platinum, become slightly magnetized when exposed to a magnetic field, but they lose their magnetism when the field is removed. When these materials are magnetized by a nearby magnet, the orientation of their north and sole poles results in their being attracted to the closest pole of the magnet.
  2. Compare diamagnetism
