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

An intensive property is a physical quantity whose value does not depend on the amount of the substance for which it is measured. For example‚ the temperature of a system in thermal equilibrium is the same as the temperature of any part of it. If the system is divided the temperature of each subsystem is identical. The same applies to the density of a homogeneous system: if the system is divided in half‚ the mass and the volume change in the identical ratio and the density remains unchanged. According

“Every man dies but not every man really lives” was among the few words written by Sir William Ross Wallace‚ an American poet during the 1860s. Well‚ as for me I want to live my life to the fullest before I leave to my eternal home up there. Having a bucket list simply keeps me on track to full fill every minor and major thing I want to do before I kick the bucket. The very first item on my list is to tell my mother that I love her. I believe in love at first sight because since the very first

“Is Density An Intensive Property Of Matter?” By: Mikal Hayden - Gates A. Introduction The first unit we learned in chemistry was Alchemy. In this unit I learned about the extensive and intensive properties of matter. An extensive property is a property of matter that depends on the changes of the substances shape or amount. An intensive property is a property of matter that doesn’t depend on the substances shape or amount. The purpose of this investigation was to prove that density is

Aims: The materials aim to cover some of the MoE’s (Ministry of Education) learning outcomes such as familiarity and correct use of parts of speech‚ syllables etc. Poetry is a Ministry curriculum genre to be used both for passive analysis as well as a productive skill and teachers shy away from it for many reasons‚ which I will deal with later. Evans (2001) proposes poetry as a good medium for teaching creative writing‚ something parents and the MoE want but schools find hard to teach.
