Formulas for calculating coils

I want to make my own application for calculation of the colis. Is there somewhere all the necessary formulas for calculations? Without them, I do not know where to start:(

I have no idea but I wanted to make sure you knew that there are apps out there.

Go to steam-engine.org
He explains everything.

You would have to calculate the circumference of the circle (the coil wrap) based on it's diameter (ID) by multiplying it by pi, double it by the number of wraps and add the legs length to get the length of the wire used, then get the resistance based on the ohm per feet value for that material and wire diameter.

And that's the easy part lol. Now try figuring out wires like fused clapton and the likes

For the core it's easy, calculate based on length of the core like you would calculate for a regular coil, then divide by number if cores.
Length of the wrap is length of the core divided by diameter of the wrap wire, multiplied by the ID, multiplied by pi, oh and don't forget the legs.
Now the difficult part is when electricity comes into play since it doesn't flow evenly through both core and wrap since they have different resistance.
