  2. Strong focusing - Wikipedia

    en.wikipedia.org/wiki/Strong_focusing

    Sextupole electromagnet as used within the storage ring of the Australian Synchrotron to focus and steer the electron beam. In accelerator physics strong focusing or alternating-gradient focusing is the principle that, using sets of multiple electromagnets, it is possible to make a particle beam simultaneously converge in both directions perpendicular to the direction of travel.

  3. Wiggler (synchrotron) - Wikipedia

    en.wikipedia.org/wiki/Wiggler_(synchrotron)

    Schematic diagram of a Halbach Array component in a free electron laser showing the orientation of magnets. A wiggler is an insertion device in a synchrotron.It is a series of magnets designed to periodically laterally deflect ('wiggle') a beam of charged particles (invariably electrons or positrons) inside a storage ring of a synchrotron.

    en.wikipedia.org/wiki/Infant_cognitive_development

    Preoperational Stage (24 Months to 7 Years) Concrete Operational Stage (7 Years to 12 Years) Formal Operational Stage (12 Years and Up) Infant cognitive development occurs in the Sensorimotor stage which starts at birth and extends until the infant is about 2 years of age. The sensorimotor stage is made up of six sub-stages.

    en.wikipedia.org/wiki/Undulator

    Working of the undulator. 1: magnets, 2: electron beam entering from the upper left, 3: synchrotron radiation exiting to the lower right An undulator is an insertion device from high-energy physics and usually part of a larger installation, a synchrotron storage ring , or it may be a component of a free electron laser .

  7. Eddy current - Wikipedia

    en.wikipedia.org/wiki/Eddy_current

    The magnetic field (B, green) is directed down through the plate. The Lorentz force of the magnetic field on the electrons in the metal induces a sideways current under the magnet. The magnetic field, acting on the sideways moving electrons, creates a Lorentz force opposite to the velocity of the sheet, which acts as a drag force on the sheet.

  8. Horseshoe magnet - Wikipedia

    en.wikipedia.org/wiki/Horseshoe_magnet

    The shape of the magnet was originally created as a replacement for the bar magnet as it makes the magnetic field stronger for a magnet of comparable strength. [5] A horseshoe magnet is stronger because both poles of the magnet are closer to each other and in the same plane which allows the magnetic lines of flux to flow along a more direct path between the poles and concentrates the magnetic ...

  9. Magnetix - Wikipedia

    en.wikipedia.org/wiki/Magnetix

    The bars with magnets at each end are 27 mm (1.1 in) long, or 68 mm (2.7 in), or 53 mm (2.1 in) and flexible, or short rigid curves. Panel shapes include two types of interlocking triangles, interlockable squares, and circle or disks. The triangles and squares identify the North-South polarity of one of their embedded magnets.
