You just described resistence.Wider structures have less inductance and the answer is: inductance is the tendency of an electrical conductor to oppose a change in the electric current flowing through it.
So, wider electrical conductor oppose less to the current flowing through it, so will have less inductance value.

Inductance is measure of how much magnetic flux is created for unit of current.
In ideal case: Ideal wire conductor with zero diameter would have largest inductance, becouse it creates large magnetic flux wery close to wire surface, where loop for flux is small and B is largest.
Lets look similiar problem: Planet A and B have the same mass but planet B have smaller diameter. So planet B have stronger gravity on the surface of planet. It's becouse surface is closer to center of planet's mass, than on planet A.
In that case, the magnetic flux between should be the same regardless of the width, isn't it?
In the end, what matters is the total loop area, right? Isn't it the same in both the cases?You miss self-inductance of each line (each of the conductors). That depends on line width, and decreases with width.

Just don't call it resistance...Resistance dissipates energy in the form of heat, inductance stores energy..It's just a misnomer, can be misleading. People tend to think that inductance is bad, which is not sometimes.- the electrical resistance of an object is a measure of its opposition to the flow of electric current.
- inductance is the tendency of an electrical conductor to oppose a change in the electric current flowing through it.
The self inductance of a wire segment (or microstrip line) is the flux linkages with that wire per unit current flowing through that wire.
Inductance L(Henry) = v/(di/dt) where v is the voltage drop across the wire segment.
Can say that inductance L is a measure of an inductor “resistance” to the change of the current flowing through the circuit, and the lower will be the rate of current change, the larger is its value in Henries.
Thicker or shorter the wire segment (or the strip line) will be less voltage drop across the segment, so will have less inductance in Henries.
Consider a round conductor. You get an axisymmetric field, flux is ~1/r. A thin conductor is inducing more voltage next to the conductor. Respectively the self inductance of a coaxial conductor geometry is ~ ln(ra/ri).
I dont think electrical parameters have virtues like 'bad' or 'good'.People tend to think that inductance is bad, which is not sometimes.
I meant, people tend to think that having parasitic inductance will screw up the performance, which is not the case. You can't look at it the same way as you look at a resistance.I dont think electrical parameters have virtues like 'bad' or 'good'.
Nope that's resistancewhen you make a narrow strip as a center conductor, you restrict the flow of electrons...which forms an inductance
