- Use the fourier transformation to determine the radial component of the magnetic field of a quadrupole.

- Relevant Equations
- Br(x) = By cos (x) – Bx sin (x)

Hello everybody!

I have a question concerning the Fourier transformation: So far I have experimentially measured the magnetic field of a quadrupole but as the hall effect sensor had a fixed orientation I did two series, one for the x, one for y component of the magnetic field, I have 50 values each.

Now I was told I had to Fourier transform these components using for Br(x) = By cos (x) – Bx sin (x). But I am not sure how to do that. I have never worked with Fourier transformations before and did some research but while I get the idea about FTs I do not know how to apply it to this very case.

I'd really appreciate any kind of help - thank you all in advance!
