measure the magnetic field

Hi everyone,

I am new with Matlab, I'm tring to measure the magnatic field in a prototype of gradient coil by using biosvat law, the problem is I need arcs instead of streight line in the attached image and I don't know how can I generate these arcs via matlab.

I used this code to simulate the wires pattern.

Looking forward for your help.

thanks in advanced.

You can have a look at this MATLAB Answer which describes on how to plot an arc: https://www.mathworks.com/matlabcentral/answers/367126-plot-an-arc-on-a-2d-grid-by-given-radius-and-end-points.

hi i'm doing the same thing as you. it's about simulating gradient coil in mri. can i ask you some quenstion?

kind regards
