How to Make Liquid Magnets - ThoughtCo

A liquid magnet or ferrofluid is a colloidal mixture of magnetic particles (~10 nm in diameter) in a liquid carrier. When no external magnetic field is present the fluid is not magnetic and the orientation of the magnetite particles is random.

Ferrofluid - Wikipedia

A ferrofluid (portmanteau of ferromagnetic and fluid) is a liquid that becomes strongly magnetized in the presence of a magnetic field. A grinding process for ferrofluid was invented in 1963 by NASA's Steve Papell as a liquid rocket fuel that could be drawn toward a pump inlet in a weightless environment by applying a magnetic field.

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 except that it's easier for the particles to change the orientation.
