Electrical Engineering - Inductors - Discussion
Discussion Forum : Inductors - True or False (Q.No. 7)
7.
Inductance is indirectly proportional to the square of the number of turns, the permeability, and the cross-sectional area of the core.
Answer: Option
Explanation:
Some factors that affect the inductance of a coil include:
1. The inductance is proportional to the square of the number of turns;
2. The inductance increases directly as the permeability of the core material increases;
3. The inductance increases directly as the cross-sectional area increases; and
4. The inductance decreases as its length increases.

L = (Uo*Ur*A*N^2)/L.
Uo = Permeability of free space.
Ur = Relative permeability.
A = Area.
N = Number of turns.
L = Length of the coil.
Uo = Permeability of free space.
Ur = Relative permeability.
A = Area.
N = Number of turns.
L = Length of the coil.

Because L = N^2UoUrA/i.
