1. Homework Statement

What is the strength of the magnetic field at the center of the loop in the figure?

See attachment

2. Homework Equations

B = Mu_0*I/(2*R)

3. The Attempt at a Solution

I plug in the information to this equation and get .00038 Tesla which is incorrect. Does the magnetic field due to a loop equation I listed above not apply to this problem?

The loop is fine, but the cable is not just a simple loop...

What is special about it?

Do you see the difference between the shape of the cable and a circle?

There is some over lap. I thought it still fitted the formula above due to the fact that it is a coil with a single turn.

I spy with my little eye: a loop and a straight wire carrying a current!

Using superposition, you will simply added the magnetic field due to the straight wire to the magnetic field due to the loop. Thank you!
