Add "Number of Turns" to Coil for Magnetic Flux Calculation.

[Martinc4321]

I'd like to propose adding a "number of turns" parameter to our coil model. Right now, we can set the inductance (e.g., 10 µH), but we can't calculate the magnetic flux directly.

By including the number of turns (N), we can compute the magnetic flux (Φ) using:
Φ=L×I/N
Φ=L×I/N

Φ: Magnetic flux
N: Number of turns
L: Inductance
I: Current

This would allow us to visualize the magnetic flux, especially when it reaches certain thresholds.

What do you think?
