Magnetic permeability of course, from the table below. The simulation is very simple, so skin effect is not modelled. Maybe I can try to simulate it with an FEA program or something like that.

Thanks! Can I get some advice on a matlab simulation of a railgun?

Not exactly inventions, but I spent time designing and 3D printing some random stuff. For example, a magnetic arm mount that lets me strap all kind of stuff to my arm, such as a metro card, or a flashlight. Other examples includes attempts to DIY a bladeless fan and a railgun, but so far they...

I was wondering about that too. But my simulation doesn't account for any inductance of the circuit, and the capacitor discharges under ideal circumstances. So, I'm not sure if an inductor is going to help with that, assuming it didn't get obliterated by the huge spike in voltage and current. I...

I'm currently studying to become a mechatronics engineer. My grades aren't all that great, but I like making inventions in my spare time. Had I encountered difficulties that tests my knowledge of physics, I would like to share it.
