Use of a solenoid for inductance

Click For Summary
SUMMARY

Solenoids are utilized as inductors due to their design, which maximizes magnetic field generation, making their effects on current and voltage more pronounced. Unlike random points in a circuit that generate localized magnetic fields, solenoids are engineered to create a strong, uniform magnetic field, enhancing their inductive properties. This design is crucial for applications requiring mechanical movement, such as activating switches. The specific geometry of solenoids allows for efficient energy storage and transfer in inductive applications.

Although I'm sure the answer is obvious, but why are solenoids used as inductors? Why don't entire circuits in general have inductor properties, since the entire circuit creates magnetic fields? More specifically, why don't random points along a circuit do the same thing as a solenoid (retain a magnetic field) since they create fields too? Is it because the solenoid is more powerful thus it affects on current and voltage are more noticeable?

Local currents in a circuit WILL induce a small amount of local magnetic field ,which usually are of no importance for the circuit.
A solenoid is a component which is designed with the specific intention of maximizing a magnetic field, often for the purpose of producing a mechanical kinetic result, such as turning a switch on or off..
