Abstract

Magnets have been known for centuries.
The Chinese and Greeks knew about the “magical” properties of magnets. The ancient Greeks used a stone substance called “magnetite.” They discovered that the stone always pointed in the same direction. Later, stones of magnetite called “lodestones” were used in navigation.




William Gilbert, an English physician, first proposed in 1600 that the earth itself is a magnet, and he predicted that the Earth would be found to have magnetic poles.

In a world of ubiquitous presence of electrons can you imagine any other field displacing it? It may seem peculiar, even absurd, but with the advent of spintronics it is turning into reality.

In our conventional electronic devices we use semi conducting materials for logical operation and magnetic materials for storage, but spintronics uses magnetic materials for both purposes. These spintronic devices are more versatile and faster than the present one. One such device is spin valve transistor.

Spin valve transistor is different from conv ....etc

Smart Cameras in Embedded Systems

Introduction
A smart camera performs real-time analysis to recognize scenic elements. Smart cameras are useful in a variety of scenarios: surveillance, medicine, etc.We have built a real-time system for recognizing gestures. Our smart camera uses novel algorithms to recognize gestures based on low-level analysis of body parts as well as hidden Markov models for the moves that comprise the gestures. These algorithms run on a Trimedia processor. Our system can reco ....etc

II. ABSTRACT
As the world continues to grow and as cities continues to become more crowded and congested, our normal modes of transportation will not be able to handle these overpopulated areas. The answer to this transportation problem lies in the world of electro magnetism and superconducting magnets. Electromagnets and superconducting magnets have allowed us to create a magnetic levitation train nicknamed “MAGLEV” that floats on the track instead of being directly on it. This has a lot of potential to creat ....etc

History of Electronics

Abstract
In this paper the history of electronics has been represented in a chronological order along with the discoverer/inventor, who actually is responsible for that. The effects of electronics on the contemporary society are very significant and without the study of the effects the history is incomplete. Thus the effects on the economy, computing and the society a ....etc

BIOMAGNETISM
INTRODUCTION
 Biomagnetism is the production of a magnetic field by a living object. The living object presently most studied is the human body, for two purposes: to find new techniques for medical diagnosis, and to gain information about normal physiology. Smaller organisms studied include birds, fishes, and objects as small as bacteria; many scientists believe that biomagnetics is involved in the ability of these creatures to navigate.
 The body produces magneti ....etc

Electricity & Magnetism


Atoms…

Have neutrons, protons, and electrons.

Protons are positively charged

Electrons are negatively charged


Electrons…

Are located on the outer edges of atoms…they can be moved.

A concentration of electrons in an atom creates a net negative charge.


Static Electricity

The build up of an electric charge on the surface of an object.

The charge builds up but does not flow.

Static elect ....etc
