Scientific definitions for magnetize


[ măgnĭ-tīz′ ]

  1. To cause an object to become temporarily or permanently magnetic. For example, an unmagnetized object made of ferromagnetic material consists of molecules that are magnetic but randomly aligned, producing no net magnetic field; exposure to a magnetic field causes the molecules to align themselves with the field, producing their own net field, so that the object as a whole becomes magnetized.
