Magnetic Susceptability Michael J. Horan II Abstract: The change in weight induced by a magnetic field for three solutions of complexes was recorded. The change in weight of a calibrating solution of 29.97% (W/W) of NiCl2 was recorded to calculate the apparatus constant as 5.7538. cv and cm for each solution was determined in order to calculate the number of unpaired electrons for each paramagnetic complex. Fe(NH4)2(SO4)26(H20) had 4 unpaired electrons‚ KMnO4 had zero unpaired electrons‚ and

Magnetic tape is a medium for magnetic recording‚ made of a thin magnetizable coating on a long‚ narrow strip of plastic film. It was developed in Germany‚ based on magnetic wire recording. Devices that record and play back audio and video using magnetic tape are tape recorders and video tape recorders. A device that stores computer data on magnetic tape is a tape drivOver years‚ magnetic tape can suffer from deterioration called sticky-shed syndrome. Caused by absorption of moisture into the binder

has a rather low intensity magnetic field. Alnico magnet alloy is now mainly used in applications where the magnet will be exposed to elevated temperatures. • Rare Earth Magnets Samarium Cobalt (SmCo) and Neodymium Iron Boron (NdFeB) are called Rare Earth because Neodymium and Samarium are found in the rare earth elements on the periodic table. Both Samarium Cobalt and Neodymium magnet alloys are powdered metals which are compacted in the presence of a strong magnetic field and are then sintered

CELLULAR RESPONSE TO IONIZING RADIATION The efficacy of diagnostic imaging resembles a double-edged sword in the medical industry. A radiographer trained to image a patient correctly must use all knowledge to keep the radiation level at its lowest and safest level to produce the best quality image possible. However‚ the radiation level still has an effect on the patient that can go unseen by the naked eye. Ionizing radiation produced by x-ray‚ gamma rays‚ alpha & beta rays‚ can have an effect

Production of magnetic flux A rotating magnetic field in the stator is the first part of operation. To produce a torque and thus rotate‚ the rotors must be carrying some current. In induction motors‚ this current comes from the rotor conductors. The revolving magnetic field produced in the stator cuts across the conductive bars of the rotor and induces an e.m.f. The rotor windings in an induction motor are either closed through an external resistance or directly shorted. Therefore‚ the e.m.f induced

The Romantic Movement emphasizes the value of individual experiences‚ the contemplation of the emotional resonance of those experiences‚ and the exhibition of those emotions. Freder and Maria‚ the main characters in the movie Metropolis‚ demonstrate these traits by freely communicating their emotions in an unnatural and technologically advanced society Freder is a Romantic Hero of Sensibility‚ a hero distinguished by a capacity for tender emotion instead of intelligence or great deeds. Freder is

NGS (AM B) A magnetic bearing is a bearing which supports a load using magnetic levitation. Magnetic bearings support moving machinery without physical contact‚ for example‚ they can levitate a rotating shaft and permit relative motion without friction or wear. In active magnetic bearings (AMB) a stable equilibrium is achieved by means of one or more control loops. The use of control loop for maintaining the gap between the shaft and bearing differentiate the active magnetic bearings (AMB)

UVA-OB-0626 RESONANCE‚ LEADERSHIP‚ AND THE PURPOSE OF LIFE I’ve always been interested in the mountains. The first time I went to Switzerland‚ I saw the mountains‚ and I said‚ “This is where I’ve got to be.” I dropped everything and found a mountain-climbing school and spent a couple of weeks in Switzerland and learned some basics of climbing‚ how to cut ice steps in glaciers and basic mountaineering. I really liked that. Clearly‚ in technical climbing you get in situations where‚ if you
