Exposure to ELF waves can induce an electric current. Because the human body is conductive, electric currents and resulting voltages differences typically accumulate on the skin but do not reach interior tissues. [22] People can start to perceive high-voltage charges as tingling when hair or clothing in contact with the skin stands up or ...
A changing electromagnetic field which is physically close to currents and charges (see near and far field for a definition of "close") will have a dipole characteristic that is dominated by either a changing electric dipole, or a changing magnetic dipole. This type of dipole field near sources is called an electromagnetic near-field.
A substantivist analysis of economics will therefore focus on the study of the various social institutions on which people's livelihoods are based. The market is only one amongst many institutions that determine the nature of economic transactions. Polanyi's central argument is that institutions are the primary organisers of economic processes.
Bioelectromagnetics, also known as bioelectromagnetism, is the study of the interaction between electromagnetic fields and biological entities. Areas of study include electromagnetic fields produced by living cells, tissues or organisms, the effects of man-made sources of electromagnetic fields like mobile phones, and the application of electromagnetic radiation toward therapies for the ...
The electromotive force generated by motion is often referred to as motional emf. When the change in flux linkage arises from a change in the magnetic field around the stationary conductor, the emf is dynamically induced. The electromotive force generated by a time-varying magnetic field is often referred to as transformer emf.
The electromagnetic force is one of the four fundamental forces of nature. It is the dominant force in the interactions of atoms and molecules. Electromagnetism can be thought of as a combination of electrostatics and magnetism, which are distinct but closely intertwined phenomena. Electromagnetic forces occur between any two charged particles.
In economics, land comprises all naturally occurring resources as well as geographic land. Examples include particular geographical locations , mineral deposits , forests, fish stocks, atmospheric quality, geostationary orbits , and portions of the electromagnetic spectrum .
In part, this name change was a response to perceived difficulties with the term home economics in a modernizing society, and reflects a recognition of human ecology as one of the initial choices for the discipline which was to become home economics. [47] Current human ecology programs include the University of Wisconsin School of Human Ecology ...
