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)

INTRODUCTION: Magnetic Resonance Imaging(MRI) is a non invasive medical imaging method widely used in hospitals and in research. In year 1946 Felix Bloch of Standard /university and Edward Purcell of Harvard University made the first succesful nuclear magnetic resonance experiment to study chemical compounds‚ they were awarded the Nobel Prize for physics in 1952. In early 1980 ’s the first human magnetic resonance imaging( MRI) scanners became available‚ producing images of the inside of the

Earth’s Magnetic Field Introduction Earth’s magnetic field is one of the world’s most complicated features. It started to be observed in 1845 by a scientist named Carl Friedman Gauss (Sarfati). The magnetic field is generated inside of the earth’s core and there are many scientists who still debate over how it was first created. There are also many arguments about the many changes that the field has gone through in it’s existence. These arguments are mostly either for a young-earth model or

JOURNAL‚ VOL. 6‚ NO. 3‚ JUNE 2006 631 Magnetic Sensors and Their Applications James Lenz and Alan S. Edelstein Abstract—Magnetic sensors can be classified according to whether they measure the total magnetic field or the vector components of the magnetic field. The techniques used to produce both types of magnetic sensors encompass many aspects of physics and electronics. Here‚ we describe and compare most of the common technologies used for magnetic field sensing. These include search coil‚ fluxgate
