Race track coil field measurements.

[SSFbloodeagleOP]

Hello, I am currently a high school student who is doing a science fair project with amperium wire, a superconducting wire, from american superconductor. I am building an elector magnet with it, it will be a race track coil type magnet for a hybrid motor. I am seeking advice on the measuring its magnetic field with an equation. I cannot afford a Gauss meter, so my best hope is to have an equation that will give me the most approximate measurement to what it would actually be so I know what to expect when I build the motor.

My current Equation I am using is B=IxNxu/L

B= tesla/gauss
I= current
N= number of turns
u= object permeability
L= length of the coil

This kind of equation would work for a solenoid with normal round wire. I am not sure it would work for a racetrack coil because the geometry is different. The wire I am using is a rectangular/ribbon type wire. It dose not have a diameter it has a length and a width.

Here is a link to a data sheet about the wire.

Due to the different shape how should I formulate this equation? Building
