  2. 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 ...

  3. Electromagnet - Wikipedia

    en.wikipedia.org/wiki/Electromagnet

    (A non-circuit example would be a magnet with a straight cylindrical core.) To determine the force between two electromagnets (or permanent magnets) in these cases, a special analogy called a magnetic-charge model can be used. In this model, it is assumed that the magnets have well-defined "poles" where the field lines emerge from the core, and ...

  4. Lodestone - Wikipedia

    en.wikipedia.org/wiki/Lodestone

    [9] [10] [11] This inhomogeneous crystalline structure gives this variety of magnetite sufficient coercivity to remain magnetized and thus be a permanent magnet. [9] [10] [11] The other question is how lodestones get magnetized. The Earth's magnetic field at 0.5 gauss is too weak to magnetize a lodestone by itself.

  5. Apex Tool Group - Wikipedia

    en.wikipedia.org/wiki/Apex_Tool_Group

    Apex Tool Group is an American supplier of hand tools and power tools. It was formed as a joint venture of Cooper Industries and Danaher by the merger of Cooper Tools and Danaher's Tools and Components segment. In October 2012, Danaher and Cooper sold Apex to Bain Capital for about $1.6 billion.

  6. National High Magnetic Field Laboratory - Wikipedia

    en.wikipedia.org/wiki/National_High_Magnetic...

    The facility houses several magnets, including a 45 Tesla hybrid magnet, which combines resistive and superconducting magnets. The lab's 41.4 Tesla resistive magnet is the strongest DC (continuous-field) resistive magnet in the world, [13] and the 25 Tesla Keck magnet has the highest homogeneity of any resistive magnet. [14]

    Cherokee Inc., also known as Apex Global Brands, is an American based global apparel and footwear company, headquartered in Sherman Oaks, California. [1] The company was established in 1973 and its brands are available in 110 countries in 12,000 retail locations and on digital commerce.

  8. Magnetic levitation - Wikipedia

    en.wikipedia.org/wiki/Magnetic_levitation

    The dimension of magnets varies between different versions, while typically in the range of 1.4 [29]-2 [28] mm square shape with a lower height. The poles of magnets were positioned as a checkerboard array to fit the magnetic field generated by the PCB platform. The robot can be built in different size depending on the size of the array.

  9. Nanomagnet - Wikipedia

    en.wikipedia.org/wiki/Nanomagnet

    Canonical single-molecule magnets are the so-called Mn 12 and Fe 8 systems, with 12 and 8 transition metal atoms each and both with spin 10 (S = 10) ground states. The phenomenon of zero field magnetization requires three conditions: A ground state with finite spin; A magnetic anisotropy energy barrier; Long spin relaxation time.
