The best way to wind copper wire around rod for lowest resistance
So I have wound 200m copper wire around a rod which gives me 180 Ω, previously I got only ~80 Ω. Both of them were randomly shuffled and the first attempt was on bigger in diameter rod. How to make ...

Why does having magnetic material in the middle of a stator help generate a current?
It seems unintuitive to me why putting a stationary hunk or iron or neodynium in the middle of a copper coil generator would increase its conductivity, because the metal could act as its own ...

Using Electricity and Magnetism to Lift non-ferromagnetic Copper Pennies
Is there any way (If you pumped a lot of current through a copper penny by shorting a circuit out through it with leads on either end) to create a magnetic field in the penny and lift it with a (very ...

Coupling mechanisms
What are some mechanisms that one material can be coupled electromagnetically to another, other than basic tranformer action?
The model I'm considering is a high current electrode, about 1.5m wide, ...
