Magnetic and Conductive Liquid Metal Gels

Oxidation and complexation reactions between the liquid metal and iron oxide nanoadditives were observed. A mixture of nanosized functional magnetic Fe 3 O 4 /Fe 2 O 3 and In–Fe oxide complexes was found to enable the magnetic susceptibility of the gels. The mechanical and self-healing properties of the gels were assessed, and …

Why do moving liquid metals generate a magnetic field?

The liquid metal allows rotational patterns that are not coaxial with the earth. In a liquid conductor, small random pockets of charge imbalance can be magnified by causing a magnetic field that creates moves other pockets in a way that magnifies the field. This can't happen in a solid. (See the answer to the second bullet above.)
