Depends on the magnetic moment of the individual atoms in the ferromagnetic material.

Silicon-iron or steel is a common ferromagnetic material with the one of the highest permeabilities and it's used in transformers and motors.

Because of the strength of the magnetic field, the ferromagnetic object was under, when it cooled from a molten state to a solid state.

As I said. Different molecular composition.. it has nothing to do with cooling in an applied magnetic field. That can be used to make magnets. But in reality most permanent magnets are made by applying a very strong magnetic field to suitable magnetic material via a high discharge current through a coil. The high remanence of the material ensures it retains the induced magnetism

Transformer and electric motor stator steels are not used in there "as melted" states. Doubtful that any ferrous metal is left in the as melted state. Transformer and stator steel goes through many different heat treating steps before being used.

But the question as posed was regarding magnets, not transformer steel. It's hard to guess what the TS was really asking.
