: I am interested in obtaining a copy or a source having a paper published in
: either 1926 or 1927 by T.F. Wall in the Journal of Instrumentation and
: Electrical Engineers on the production of intense magnetic fields. Any
: help will be greatly appreciated.
Unfortunately, I don't have a copy of this paper. The journal in which it was published apparently was somewhat obscure, published in London, and I've been unable to locate any academic on-line literature database that contains it. A technical university librarian (in Great Britain?) may be able to help you locate a copy.
There are some other contemporary articles and books authored by T. F. Wall that may be helpful. These include:
“The Production of very Intense Magnetic Fields” (1924), TF Wall, Nature 114, 432 (20 September 1924)
“Intense Magnetic Fields and the Disturbance of Electronic Orbits in Magnetic Materials”, Letters to the Editor, Nature 113, 568-568 (19 April 1924), http://www.nature.com/nature/journal/v113/n2842/pdf/113568a0.pdf

Good luck - if you happen to locate a copy of this paper, please let me know.
