INTRODUCTION

Biomagnetism is a combination of two sciences Physics and Biology. It is a new field of scientific research evolved after the major discovery of biomagneticfield resulting from bioelectric currents or magnetization biological tissues. It deals with the study of magnetic contaminants of the body.

Science of biomagnetism applies a technology that was originally developed for the measurement of extremely weak signals. Biomagnetism can change and elevate the electric currents and cellular charges thereby in ....etc

Psycho Physiological Credibility Assessment
INTRODUCTION
Lies are part of human life! People often tell lies to deceive others. many of us have heard about lie detector ,some where seen in movies or read it in fiction stories. Does anything of this sort really exist? If yes, does it really detect lies? Yes it does. The first thing that comes to our mind is how an instrument with some electronic components can read out our mind. Though science and technology are growing at the speed of light, has it reached a stage whe ....etc

Production Of Bioelectricity
INTRODUCTION:
Fossil fuels have supported the industrialization and economic growth of countries during the past century, but it is clear that they cannot indefinitely sustain a global economy. The infrastructure changes needed to address our global energy needs will be far more extensive and will likely require changes not only to our infrastructure but also to our lifestyle. Changes will affect everything from home heating and lighting, to where we prefer to live and work and how we get t ....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
