on Magnet materials • Alnico Magnets Alnico magnet alloy is largely comprised of Aluminum‚ Iron‚ Cobalt and Nickel. Alnico is a moderately expensive magnet material because of the Cobalt and Nickel content. Alnico magnet alloy has high maximum operating temperature and a very good corrosion resistance. Some grades of Alnico alloy can operate upwards of 1000C. Magnets made with this alloy are available in a variety of grades and dimensions and they are usually cast. Alnico magnet material is an older

SMART MATERIALS 1. Introduction The primary characteristic of a ‘‘smart material’’ is that it has the ability to respond to external stimuli in a technically useful and technically controlled way. The words ‘‘technically useful’’ and ‘‘technically controlled’’ are emphasized since all materials respond to external stimuli of some sort or other (as a simple example‚ all materials respond to temperature by changing their volume)‚ however‚ to be considered a ‘‘smart material’’ the response must

Photosensitive materials (x-ray films) are used to record the invisible x-ray image. It is required to reproduce all the characteristics of the invisible image in visible form .The films ability to do so depends on its sensitometric properties. Sensitometer: Measures films sensitivity to light; shows the range of densities on an image. Sensitometry:- The scientific study of the response of photosensitive material to different levels of exposure. How is it done? Producing a sensitometric strip

Evans (2001) proposes poetry as a good medium for teaching creative writing‚ something parents and the MoE want but schools find hard to teach.
