affected by the presence and motion of such particles. A changing magnetic field produces an electric field (this is the phenomenon of electromagnetic induction‚ the basis of operation for electrical generators‚ induction motors‚ and transformers). Similarly‚ a changing electric field generates a magnetic field. The magnetic field is produced by the motion of electric charges‚ i.e.‚ electric current. The magnetic field causes the magnetic force associated with magnets. The theoretical implications

Abstract α-amylase was immobilized covalently on iron oxide magnetic nanoparticles. The synthesis of magnetic nanoparticles was done by the coprecipitation conventional method. The chemical composition and particle size of the synthesized particles was confirmed via X-ray diffraction. Tyrosine‚ Lucien and chitosan and glutaraldehyde were investigated to make a covalent binding between the iron oxide magnetic core and the immobilized enzyme. Immobilization using chitosan and glutaraldehyde show

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

Magnetic Storm This video is about the Earth’s magnetic force and its wavering. The molten iron in the earth creates the magnetic force around the earth. The magnetic force protects the earth‚ making it possible for life to exist on the planet‚ unlike other planets with weaker magnetic forces. Recently‚ though‚ scientists have discovered that the magnetic field seems to be faltering. The magnetic force starts near the South Pole and extends around the earth close to the North Pole and shields

.INTRODUCTION Magnetic levitation is the latest in transportation technology and has been the interest of many countries around the world. The idea has been around since 1904 when Robert Goddard‚ an American Rocket scientist‚ created a theory that trains could be lifted off the tracks by the use of electromagnetic rails. Many assumptions and ideas were brought about throughout the following years‚ but it was not until the 1970’s that Japan and Germany showed interest in

An Analysis on Thompson‚ Rindfleisch‚ and Arsel’s “Emotional Branding and the Strategic Value of the Doppelganger Brand Image” Emotional branding has never been a topic that I have ever had a conversation about nor have I cared much about it. After reading this article I have learned a great deal about emotional branding versus the significance of the doppelganger brand image. Even after reading both sides of the story I believe that there is a need in our society for both aspects. The
