If you do that, you'll figure out that there is definitely an eclectic field. Where E = kQ/(r^2) First things first, let's get r. Since we have a square, and our point of interest is the center of the square. Use a^2 + b^2 = c^2 to get the length of the diagonal. Half that distance is the location of the center point, for all four corners of the square. Next, figure out an Electric Field for one of the corners, pick one, it ...

Solve by plugging into the equation I=F/(B*l*sin0).

I = Current
l = Wire Length
B = Magnetic Field
F = Magnetic Force on the Wire
0 = Angle made with the magnetic field (and thereby paper plane - horizonal positive axis)
