    Abstract: A sphere device with a magnetic field is configured to be detected by a magnetic sensor and has a spherical housing, a magnetized core, and a magnet unit. The spherical housing is hollow and is made of a non-magnetic material. The magnetized core is made of a magnetic material and is fixed in the spherical housing. The magnet unit is disposed in the spherical housing and magnetically attached to an external surface of the magnetized core to magnetize the magnetized core. Therefore, a magnetic field around an external surface of the sphere device has less weak region and is easily detected by a magnetic sensor while the sphere device is reaching the magnetic sensor.

    Abstract: The present disclosure provides an inspection system and a method of stray field mitigation. The system includes an array of electron beam columns, a first permanent magnet array, and a plurality of shielding plates. The array of electron beam columns each includes an electron source configured to emit electrons toward a stage. The first permanent magnet array is configured to condense the electrons from each electron source into an array of electron beams. The first permanent magnet array is arranged at a first end of the array of electron beam columns. The plurality of shielding plates extend across the array electron beam columns downstream of the first permanent magnet array in a direction of electron emission. The array of electron beams pass through a plurality of apertures in each of the plurality of shielding plates, which reduces stray magnetic field in a radial direction of the array of electron beams.

    Abstract: An organizer for a plurality of metallic objects has a nonmetallic housing and a magnetic core. The nonmetallic housing has opposing top and bottom external surfaces. A ridge projects from a periphery of the top external surface. The magnetic core attracts metal towards the geometric center of the top external surface and towards the ridge at the periphery of the top external surface. In some implementations, portions of the magnetic field attract metal in the directions: (i) perpendicular to the geometric center of the top external surface; (ii) outward from the geometric center of the top external surface; and (iii) toward the ridge on the top external surface. Implementations have the magnetic core with a square cross section and north and south poles separated by a distance substantially less than the width of the substantially square cross section, and with its magnetic field in the shape of a torus.

    Abstract: A method of producing an oppositely magnetized magnetic structure within or on a substrate material includes: generating first and second numbers of cavities within or on a substrate material and filling the first and second numbers of cavities with first and second hard magnetic materials, respectively exhibiting first and second coercive field strengths, wherein the second coercive field strength is smaller than the first coercive field strength. The method further includes magnetizing, in a first direction, the first and second arrangements of magnetic structures, by a magnetic field having a field strength that exceeds the first and second coercive field strengths. The method further magnetizes the second arrangement of hard magnetic structures in a second direction, which differs from the first direction, by a second magnetic field having a field strength below the first coercive field strength but greater than the second coercive field strength.
