These phenomena all contribute various field components to the biofield. This article describes the present status of research on biomagnetism an interdisciplinary field of research involving biology engineering medicine physics psychology and other areas. Measurement of magnetic field produced from the human body abstract. Magnetometer is used for low magnetic field measurements of value less than 1mt. As all electricity does this activity also creates a magnetic field. Links to useful measurements.
The first valid measurement was actually made in 1963 but the field of research began to expand only after a low noise technique was developed in 1970. These techniques measure the magnetic fields produced by the electrical activity in the body. But the laws of physics demand that any electrical current generates a corresponding magnetic field in the surrounding space. Gaussmeter is used for high magnetic field measurements of value greater than 1mt. The biomagnetic fields of the body though extremely tiny have been measured with techniques including magnetoencephalography meg and magnetocardiography mcg. The meg shows complementary information to the electroencephalogram eeg and is producing valuable new information about the normal human brain.
The electrical and magnetic fields of the human body are complex and dynamic and are associated with dynamical processes such as heart and brain function blood and lymph flow ion transport across cell membranes and many other biologic processes on many different scales. The present scientific definition took form in the 1970s when an increasing number of researchers began to measure the magnetic fields produced by the human body. Most measure the magnetic field from the brain called the magnetoencephalogram or meg. As all electricity does this activity also creates a magnetic field. It is very important to perform magnetic field measurement as it is very costly and difficult task to mitigate or reduce magnetic field interference. The human body produces complex electrical activity in several different types of cells including neurons endocrine and muscle cells all called excitable cells.
There are about 160 laboratories around the world where fields from various parts of the body are measured. The human energy field it has long been known that activities of cells and tissues generate electrical fields that can be detected on the skin surface.
