B-field from a current in a wire above a conducting surface

[Sidsid]

Homework Statement

What is qualitatively the difference between the magnetic field of an infinite current wire and one with the addition of an infinite , neutral, conducting surface under it. Find it for points between them,under the surface, and above the wire. The magnetic field is 0 at the conductor.

Relevant Equations

B= (mu_0* I)/(2pi r) (circumferential)

I first thought of imaging techniques, because the setup reminded me of it, but i have only ever seen those of electrostatics. If i for example add a current in the opposite direction and with the opposite heigth of the surface the fields dont cancel out at the surface, i think. What is the best approach?

Yes. Use imaging techniques.
