**1. Homework Statement**

For the current element Idx(ax+ay) A situated at P(1,-2,2), find the magnetic flux densities at P(2,-1,3).

**2. Homework Equations**

Biot-Savart

dB = (K)(IdI x r)/rr

**3. The Attempt at a Solution**

my only problem in here is that i'm having a hard time figuring out what idx is? do i just substitute it for Idl then just get its cross product with r and so on? also, do i need to actually integrate it to get B?

that is all and thanks.
