production of certain niche MRAM products over the next several years. WHAT IS MRAM? MRAM is a non volatile random access memory which uses magnetic storage and Magneto resistance(MR) to read the stored data. Magneto resistive material is a resistor made of common ferromagnetic material which will change in resistance in the presence of a magnetic field. The magneto resistive property gives a small but sufficient signal to

Headphones would not have been invented had it not been for the revolutionary combination of beneficial concepts in both electricity and magnetism. Not that much of a scientific fiction anymore‚ hovering vehicles seem achievable through magnetic levitation using Lenz’s law‚ as demonstrated by the already existing maglev trains in Japan‚ South Korea‚ and China. It is true that power supply is problematic and expensive. However‚ it is a decent beginning that shows the possibility of having

(CETS)‚ by which electrical energy may be transmitted‚ without electrical connection or physical contact‚ through nonmagnetic media of low conductivity. The CETS‚ which has been used to transfer up to 5 kW across a 10-mm gap‚ employs high-frequency magnetic coupling and enables plug-in power connections to be made in wet or hazardous environmental conditions without the risk of electric shock‚ short circuiting‚ or sparking. Energy may be transmitted without the necessity for accurately manufactured

An Observation of Borderline Personality Disorder Observation The first time I heard the phrase “mommy dearest” was when I was in Junior high school. My classmates were joking around about how their mother’s yelled and lecture them and telling stories. Jokingly‚ one of my classmates suddenly yelled out “mommy dearest” and they started to laugh. I vividly remember thinking at that time‚ what’s mommy dearest? And what does that mean‚ am I missing out on something that everyone already knew

This poem was inspired on an article published by the New York Times‚ which reflected the injustice that blacks received from the whites during the apartheid years. From the very first line we can see the implications of racism since we are told what gender and ex-job the policeman had while we not given any information about the black discriminated woman. The ex-policeman is set on a higher category as if he was superior. "A pregnant Black was Heart Donor; Recipient in Capetown a White Ex-policeman

There will be a magnetic field developed in the stator. Now rotor of motor that is made up of permanent magnet‚ will try to move with the revolving magnetic field of stator. This is the basic principle of working of stepper motor. Now we are going to discuss its types. In this note you will find the real method of working of specific type
