Could a magnetic field stablize liquid metal in space to make a liquid shield?

Liquid metal would form a ball similar to water at 0 gravity.



Could liquid metal be made ferromagnetic by externally inducing an internal magnetic field to form a stronger liquid metal ball?



Could hot liquid iron or lead close to the sun be held together by an artificial magnetic field to make a solar shield?



To farther this question: Can a metallic gas cloud be contained using a magnetic field while traveling in space?

Could liquid metal be made ferromagnetic by externally inducing an internal magnetic field?




No. Metal is either ferromagnetic or not; this is a result of the quantum-mechanical interaction of neighbouring atoms in the metal's crystal lattice. Even non-magnetised iron at room temperature is ferromagnetic, only, the Weiss domains are randomly oriented and mostly cancel out, which can be changed by applying an external field to orient them all in the same direction. Most other metals aren't ferromagnetic and an external field can't do anything about this: there are no magnetic domains that you could align in some way. And as Uwe commented, even the ferromagnetic metals are only ferromagnetic below the Curie temperature. This always lies below the melting point, so no: liquid metals can not be made ferromagnetic.



But I don't think that's really what you meant to ask anyway: ferromagnetism is not the only way metals can interact with magnetic fields. There are three other mechanisms:





  • Paramagnetism is similar to ferromagnetism, except you don't have mesoscopic magnetic domains that could be aligned, but only microscopic spins of single atoms or molecules. Thus, paramagnets are attracted to magnets similarly as ferromagnets are, just much weaker.

    Many materials are paramagnetis, including liquids. Often they aren't metals, e.g. liquid oxygen is an example.


  • Diamagnetism is even weaker, and has the opposite effect: diamagnets are repelled by an inhomogeneous magnetic field.


  • Induction. Any conductor, and thus any metal even if liquid, will respond to a time-variable magnetic field: such a field generates currents, and those currents will broadly speaking reject the field-change. And this can indeed be used to move/shape the conductor without touching it. It is mostly important for plasma (conductive gas), and is the working principle behind Tokamak and Stellarator fusion reactors.


So, induction is your best bet. Could this be used to form a shield? Possibly. In fact fluid conductors have a natural tendency to form sheet-like structures. Whether this is practical is dubious, but it's in principle a worthwhile idea.
