This effect, they said, is likely to cause metallic core material to infiltrate parts of the lowermost mantle. "If true, the results suggest iron from the core has been leaking into the mantle for ...
Perhaps more importantly, it will give planetary scientists a chance to study an iron core like the one located in the center of the Earth—and uncover a new kind of metal world in the solar system.
A coil with an iron core is called an electromagnet. The iron core increases the coil’s magnetic field strength. A simple electromagnet is made by coiling wire around an iron nail. An iron core ...
The Earth's inner core was once liquid, but has turned solid over time. As the Earth gradually cools, the inner core expands outwards at the surrounding iron-rich liquid "freezes." That said, it ...
The strength of the electromagnet can be increased by passing more electric current through the coils and/or wrapping more coils around the iron core. Electromagnets are used in devices such as ...
