Melting metal with magnets materials
WebAlnico is a family of iron alloys which in addition to iron are composed primarily of aluminium (Al), nickel (Ni), and cobalt (Co), hence the acronym al-ni-co.They also include copper, and sometimes titanium.Alnico alloys are ferromagnetic, and are used to make permanent magnets.Before the development of rare-earth magnets in the 1970s, they … WebYes, magnetism in a metal is sustained by the fact that aligned magnetic moments of grains and individual atoms and electrons cannot randomly dissipate by rearrangement. …

Webwhere J and B are the current density and magnetic-induction fields, respectively, and is the electric conductivity. Also, to arrive at Equation 3, use has been made of Ohm's law for a moving conducting fluid. J = ( E + u x B) (4) Two types of magnetic fields are applied in solidification processes for molten metals and semiconductor melts. WebThe Curie temperature of all sensible materials is and has to be below the melting point. When you approach the melting point while heating the material, the magnetism has been lost for quite some time. Yes, molten iron is paramagnetic, much like every ferromagnetic material above the Curie temperature. Share Cite Improve this answer Follow
