Ans - this describes a material that doesn't retain it's magnetic property even when the magnetic field has been removed, an example is Aluminum. Diamagnetic materials are repelled by a magnetic field; an applied magnetic field creates an induced magnetic field in them in the opposite direction, causing a repulsive force. Magnetic character - If all the electrons in the molecule of a substance are paired, the substance is diamagnetic (repelled by the magnetic field). I'll tell you the Paramagnetic or Diamagnetic list below. KO2 is the formula paramagnetic and because potassium is +1, the superoxide has a charge of -1.
