I Creating any shape of a magnetic field?

  1. Aug 28, 2018 #1
    I was wondering if it was possible to create any shape of magnetic field. If yes, what would it take to do so?

    What about if I wanted a certain magnetic field in a constrained/finite area?

    No. The magnetic field is constrained by Maxwell's equations. For instance, it is impossible to create a maximum of the magnetic field in free space.

    Unfortunately, I don't think so.

    This question is far too general for a sensible answer. You haven't specified what you want but there are many applications foe magnetic fields that require some weird field patterns. I'm thinking, in particular, about the requirement to form well controlled beams of electrons in old fashioned Cathode Ray Colour display tubes. The original 'shadow mask' type tubes needed to use very long beam paths in order to make the RG and B beams properly converge and to get pure colours. Designers got more and more inventive with the shaping of the scanning magnetic fields and managed to achieve the same quality with ever shallower tubes with 'flatter' screens.
