  • Method and apparatus for magnetizing a permanent magnet
    Publication number: 20040074083
    Abstract: A method of making a permanent magnet body is provided. The method includes providing a first precursor body comprising a plurality of blocks and magnetizing the first precursor body to form a first permanent magnet body. A recoil magnetization pulse may be applied to the permanent magnet body after the magnetization. The precursor body may be heated during magnetization. A power supply containing a battery may be used to energize a pulsed magnet used to magnetize the precursor body.
    Type: Application
    Filed: October 10, 2003
    Publication date: April 22, 2004
    Applicant: GENERAL ELECTRIC COMPANY

  • Permanent magnet assembly and method of making thereof
    Publication number: 20030090354
    Abstract: An imaging apparatus, such as an MRI system, contains at least one layer of soft magnetic material between the yoke and each permanent magnet. This imaging apparatus may be operated without pole pieces due to the presence of the soft magnetic material. The permanent magnets may be fabricated by magnetizing unmagnetized alloy bodies after the unmagnetized alloy bodies have been attached to the yoke.
