Why someone might use an air iron or ferrite core in an inductor?

Iron core inductors are better at storing magnetic energy than air core inductors as the iron material helps amplify the inductor’s magnetic field. This in turn allows an inductor with an iron core to store more magnetic energy compared to an inductor with an air core with the same number of turns.

Core memory uses toroids (rings) of a hard magnetic material (usually a semi-hard ferrite) as transformer cores, where each wire threaded through the core serves as a transformer winding. Two or more wires pass through each core. Magnetic hysteresis allows each of the cores to “remember”, or store a state.
