iron core
Transformer's metallic heart
An iron core is a solid piece of iron at the center of something, typically an electromagnet, transformer, or motor, where it concentrates and strengthens magnetic fields.
Earth's iron core—its innermost layer—generates the planet's magnetic field.
The term appears in physics and geology with slightly different referents but the same basic image: iron at the center.
