Magnetohydrodynamics from a blacksmith´s perspective

Summary form only given. The substantial forces available through the use of magnetohydrodynamics (MHD) find diverse uses in the field of metallurgy. The author describes three of these: two have undergone benchscale development and one awaits development of the requisite critical field strength capabilities in high-temperature superconductors. All three devices depend upon a very simple concept. When a current-carrying conductor, is crossed by a magnetic field, an MHD body force (the Lorentz force) is exerted on that conductor. Two of the three devices to be discussed utilize the application of that force to molten metals. The third device utilizes the force as a magnetic pressure against a solid metallic surface
