Find magentic field intensity.

Homework Statement

A square with each side of 5 cm in length.Now if 4 parallel wires in each 4A current is flowing were placed on the vertex of the square.How can I find the center of the square of the magnetic strength?

Homework Equations

I am not sure what equation should be used.If I knew I would solve the problem myself.

The Attempt at a Solution

Since the wires are placed at the corners i.e vertex of square, then the 4 wires will make another square like structure.

If it were only one wire placed at a corner, what would be the magnetic field vector at the square center?

Hi Julian102,

Use the "UPLOAD" button to copy an image file from your machine to the PF site. Then there won't be access problems for displaying the image (a file on your machine's desktop is not accessible to all, so a link to it fails).
