Magnetic field of a ferrite core solenoid
When the iron core is added, the inductance of the solenoid increases and we had to pump more energy into the solenoid to produce this 1A steady state — so perhaps it''s not surprising that the field is stronger outside the solenoid.

Energy storage in a transformer core is an undesired parasitic element. With a high permeability core material, energy storage is minimal.

Differences between Air-Core and Iron-Core Inductors
Inductors, or "coils," are used in electrical circuits to store energy in a magnetic field. There are two types of inductors: air-core and iron-core. The primary difference between them is the material used to create the core. Air-core inductors use a hollow, non-magnetic core, usually made of plastic, ceramic, or some other insulating material. They have low inductance values …

Inductor
An inductor, also called a coil, choke or reactor, is a passive two-terminal electrical component that stores electrical energy in a magnetic field when electric current flows through it. An inductor typically consists of an insulated wire wound into a coil around a core. When the current flowing through an inductor changes, the time-varying magnetic field induces a voltage in the …

Air Core vs Iron Core
So apparently, when air core get to large and expensive, it is time to consider switching to iron/powered/laminated core coils. I assumed I was safe at 800hz, but today''s design are more often low-bass, midbass, tweeter rather than woofer, midrange, and tweeter, so the low-to-mid crossover is substantially low. I think I''ve seen crossovers in the 250hz to 350hz …

Crossover Inductors
An air core must have huge wire to have a low DCR, because it must have more turns for a given inductance value. The purpose of a core is to permit a shorter wire to produce the same inductance with fewer turns. So the compromise is size and cost, air core costs more because it has more copper compared to a ferrite or iron core.
