MAGNETIC MAGNETIC REFRIGERATION a fruitful approach to reduce environmental pollution... ABSTRACT : The objective of this effort is to determine the feasibility of designing‚ fabricating and testing a sensor cooler‚ which uses solid materials as the refrigerant. These materials demonstrate the unique property known as the magneto caloric effect‚ which means that they increase and decrease in temperature when magnetized/demagnetized. This effect has been observed for many years and was used for cooling

INTRODUCTION In the recent years‚ technology continues to evolve and improves its capability affecting every individual’s daily routines. Technology has impacted the different facets of life and certainly changed and redefined the way we live (Oak‚ 2011). One of the most common technologies used by people around the globe is computer. According to International Telecommunications Union or ITU‚ in 2010‚ the ratio of Filipino computer users over the Philippines’ population results in 29‚700‚000

TYPES OF MAGNETIC MATERIALS Paramagnetic materials have a small‚ positive susceptibility to magnetic fields. These materials are slightly attracted by a magnetic field and the material does not retain the magnetic properties when the external field is removed. Paramagnetic properties are due to the presence of some unpaired electrons‚ and from the realignment of the electron paths caused by the external magnetic field. Paramagnetic materials include magnesium‚ molybdenum‚ lithium‚ and tantalum

Preservation of Forests resources Several measures have been prescribed for the preservation of the forests. They are as follows: The trees cut down for timber or other uses‚ should be matched with planting of more trees‚ so that‚ there is no scarcity. The use of fuel wood and wood charcoal should be discouraged. The conventional sources of energy should be tapped. Biogas should be employed for cooking‚ to lessen the consumption of fuel wood. Modern methods of forest management should be

octacyanomolybdate(IV) anions‚ Mo(CN)84-‚ of approximate dodecahedral‚ D2d‚ and square antiprismatic‚ D4d‚ symmetry. The sensitivity of the Mo magnetic shielding (σ) and electric field gradient (EFG) tensors to small changes in the local structure of these anions allows the approximate D2d and D4d Mo(CN)84- anions to be readily distinguished. The use of high applied magnetic fields‚ 11.75‚ 17.63 and 21.1 T‚ amplifies the overall sensitivity of the NMR experiment and enables more accurate characterization of

Electro Discharge Machine and how it functions and what is needed to make it function Electro Discharge Machining (EDM) is a process‚ where we use the electrical energy to produce electrical waves and thermal energy to mould any alloy into a desired shape/size. This machining method can only be used with materials that conduct electrical energy well. EDM is so powerful that it can cut through into hard steel without the need to soften it. This method is not only used to shape steel but it

Magnetic particle inspection (MPI) - Is a non-destructive testing (NDT) process for detecting surface and slightly subsurface discontinuities in ferroelectric materials such as iron‚ nickel‚ cobalt‚ and some of their alloys. The process puts a magnetic field into the part. The piece can be magnetized by direct or indirect magnetization. Direct magnetization occurs when the electric current is passed through the test object and a magnetic field is formed in the material. Indirect magnetization occurs
