Multi turn winding inductance
The inductance of multi turn winding can be calculated with DC magnetic module of QuickField. We may consider a multi turn winding as several single turns connected in series. Let's start with the singleturn winding:
Inductance of the single turn winding can be obtained from the equation:
L = ψ / i, where ψ  is a flux across the winding.
To calculate the magnetic flux in QuickField you should use the integral calculator:
Multiturn winding, considered as a series of singleturn windings, may be shown as:
Magnetic flux linked with each turn is Φ = n·ψ. The single turn inductance is:
L_{1} = Φ / i
Multi turn winding inductance (series connection):
L_{n} = n·L_{1} = n · Φ / i = n · n·ψ / i = n^{2} ·ψ / i = n^{2} · L
Multi turn winding inductance (parallel connection):
L_{n} = Φ / I = n·ψ / n·i = ψ / i = L
The inductance of multi turn winding (with n turns connected in series) can be obtained by following algorithm:
 Replace multi turn winding by single turn with total current I = n·i.
 Calculate magnetic flux Φ.
 Calculate inductance of the single turn L = Φ / I.
 Multiply inductance by the n^{2}.
