Vector potential

  1. Jan 29, 2005 #1
    The vector potential (A) in a certain region is given by A = xj-yi where i and j are unit vectors.

    How will the lines of force look like?

    What is the direction of magnetic induction B in the given region of space?

    How about computing the curl and setting it equal to B?

    Can please you explain me how you do that? Can you point out to me a chapter in Griffith's book which might help?

    Yes,it surely is the one in which this pops up

    [tex]\vec{B}=\nabla\times \vec{A} [/tex]

    Yes, but how does it explain the lines of force?

    Find the vector fields,its components and then u know that this vector field is always tangent to its lines of force...
