Re: Building Electromagnets with High Field Intensities

  1. Jun 12, 2007 #1
    Hi All,

    From "http://en.wikipedia.org/wiki/Electromagnet", they say that it's impractical to build electromagnets with high field intensity (i.e. over 787 Amp-turns/meter becuase most ferromagnetic materials saturate at around 1-2 teslas. However, when I performed computer simulations of the fields produced by electromagnets of over 200 000 Amp-turns with a ferrous core of 10 cm by 10 cm, the field created can reach above 3 Teslas. Is there a problem with the simulation program? Am I not understanding some concepts correctly?
