    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.

    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.

    Resting heart rate is usually between 80 and 160 beats per minute, and it typically stays within that range until the infant is about one year old. [18] Motor development. Can hold up head and chest while in prone position. [24] Movements of arms and legs become smoother. [25] Can hold head steady while in sitting position. [24]

  5. 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.

    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 .

  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. Samarium–cobalt magnet - Wikipedia

    en.wikipedia.org/wiki/Samarium–cobalt_magnet

    A samarium–cobalt (SmCo) magnet, a type of rare-earth magnet, is a strong permanent magnet made of two basic elements: samarium and cobalt.. They were developed in the early 1960s based on work done by Karl Strnat at Wright-Patterson Air Force Base and Alden Ray at the University of Dayton.
