Concept:
The inductance of a coil is given by:
N = number of turns in the coil
A = Area of the cross-section
l = length of the coil
μ = magnetic permeability of the coil
Application:
With N2 = 2 × N1, A2 = A1 and l2 = l1
∴ If the number of turns in a coil is doubled in the same length and area, the inductance L will quadruple.
