  • Magnetic Materials

    Diamagnetic materials have a weak, negative susceptibility to magnetic fields. Diamagnetic materials are slightly repelled by a magnetic field and the material does not retain the magnetic properties when the external field is removed. In diamagnetic materials all the electron are paired so there is no permanent net magnetic moment per atom.

  • Magnetic-core memory - Wikipedia

    Magnetic-core memory was the predominant form of random-access computer memory for 20 years between about 1955 and 1975. It was part of a family of related technologies which bridged the gap between vacuum tubes and semiconductors by exploiting the magnetic properties of materials to perform switching and amplification. Such memory is often just called core memory, or, informally, core.
