Magnétisme (in French)

Très bien, peut servir chez nous aussi.

I would like to add some comments in English..

For your Python code it is better to read the data prepared as an ASCII file using np.loadtxt() - see a zip file that I have attached. So one should not change the code every time. I have allowed myself to replot your data... The code is simple, but not all our students can reproduce it.

It would be maybe better to use a smaller NdFeB magnet to approach it closer in order to have a larger interval of the distance r. One have to pay attention to  fridge magnets, they are usually magnetized in an alternating way to hook better (Halbach magnets).
