Electric Quadrupole

  1. Apr 16, 2010 #1
    Hi All,

    I'm looking for a figure from a textbook which showing the field lines of a quadrupole. The quadrupole i'm looking for is four charges arranged on the corners of a square, 2 diagonal -ve charges and 2 diagonal positives. Please let me know if you have seen such a fieldlines in any text book.

    The figure i'm looking for is exactly as the attachment, but I need to find such a figure in a textbook.

    Thanks

    Look in a textbook on mass spectrometry ... the quadrupolar field is very important there, and pretty much any text will have an illustration in the introductory chapters.

    Thanks for your reply. I'm not an electrical engineer or physicist, am a microfluidics expert, thus I'm not familiar with these topic, do you recommend a specific book?

    Best,
