Liquid Iron Magnetic

Physics - Focus: Molten Metal Magnet

Jan 30, 2007· But Earth’s core, a rotating mix of iron and nickel with internal flows driven by the passage of heat, has no battery and no wires. Instead, it creates magnetism by means of self-sustaining feedback. Liquid metal moving through a magnetic field generates a current, similar to that induced in the moving coil of an electric generator.

Will molten iron stick to a magnet? - Physics Stack Exchange

The loss of magnetism at the Curie temperature applies primarily to "induced magnetism like iron sticking to a magnet".. Ferrofluid doesn't really include a molten iron; ferrofluid is a collection of many small but mezoscopic particles, "sawdust", and its magnetism doesn't differ so much from magnetism of normal pieces of iron …

How To Make Magnetic Slime - ThoughtCo

Ferrofluid is more liquid than magnetic slime, so it forms better-defined shapes when exposed to a magnetic field, while silly putty is stiffer than the slime and can crawl slowly toward a magnet. All of these projects work best with rare earth magnets rather than iron magnets.

9.3 Earth’s Magnetic Field – Physical Geology

9.3 Earth’s Magnetic Field Heat is also being transferred from the solid inner core to the liquid outer core, and this leads to convection of the liquid iron of the outer core. Because iron is a metal and conducts electricity (even when molten), its motion generates a magnetic field.

Magnetism - Wikipedia

Magnetism is a class of physical phenomena that are mediated by magnetic fields. Electric currents and the magnetic moments of elementary particles give rise to a magnetic field, which acts on other currents and magnetic moments. The most familiar effects occur in ferromagnetic materials, which are strongly attracted by magnetic fields and can be magnetized to become permanent magnets ...
