Hi, I need help with writing mathematical model of experiment that demonstarate Lenz-s law (the magnet trough copper tube).

I want to write the model and simulate it in matlab/simulink. On the following link

https://brilliant.org/wiki/lenzs-law/ there are a mathematical equitions, but i have problem to prepare them for simulink. I want to monitor distance r or force F, or speed v(t) from the maentioned equtions?

Can you help me with this, or do you know if there is simmilar model already done in simulink?

Best regards
