Glossary
The bioelectromagnetics study and apply the interactions between biological systems and electromagnetic fields. Electromagnetic field (EMF) It is a combination of an electric field and magnetic field that can spread through a mechanism wave (wave) when it becomes electromagnetic radiation.
MAGNETIC FIELD
Spatial distribution of forces between magnets or between alternative sources of power alternating magnetic field. The magnetic field exists only when a flow of electrons spreads. (See electric charge).
ELECTRICAL LOAD
The electric charge is a basic property of fundamental particles that occurs as integer multiples of charge of a proton (positive, negative or zero). It is detected by the mechanical force between charges. A electrostatic field is a property of electric charge in uniform motion. (A radiation (wave) is the property of electric charge accelerated or decelerated).
CONSISTENCY
It is an expression of the degree of constancy of phase, for example between two oscillators or between two waves considered as having the same frequency. It is a measure of the extent to which perfect consistency is reached.
DUALITY WAVE / PARTICLE
Particulate material may not be adequately described only by admitting that they have both properties of waves. The wave amplitude (according to De Broglie) can be regarded as the probability of finding particles in a given position at a given moment.
ENERGY
The capacity of a system to provide mechanical work or its equivalent. In electricity, it is the work associated with moving electric charge in the presence of an electric field. The work unit is the joule.
ENTROPY
It is a measure of disorder of a system. It is expressed by the energy that can be absorbed by a system divided by its absolute temperature.
FREQUENCY
The number of cycles of vibration per second (by extension the number of times a phenomenon occurs over a period of time). An oscillator is a frequency generator.
GIGA
Prefix denoting one billion times the basic unit (eg 1 GHz = 1,000,000,000 Hz).
WAVELENGTH
The distance between two successive peaks of a wave. The wavelength in meters multiplied by the frequency (Hz) gives the velocity of wave propagation in meters per second.
MAGNETISM
Phenomenon occurring in the space surrounding moving electric charges in a closed circuit (cable or coil - magnet) or a field of interaction of charges circulating in orbit or turn on themselves in an atom or molecule (permanent magnet).
MEGA
Prefix denoting one million times the basic unit (eg 1 MHz = 1. 000. 000 Hz). MICRO Prefix designating the millionth part of the basic unit (eg 1 micron = 1 micrometer)
MICROWAVE
Electromagnetic radiation whose wavelengths are of the order of the dm cm or mm. These rays are used for cooking due to energy absorption by water molecules. (ovens, microwaves, also known as 'Microwave', using the frequency of 2, 45 GHz). It also uses microwaves to radar and mobile telecommunications, cellular and satellite networks) due to the fact that they can be run in very narrow beams.
ION A
single electron or a positron or an atom or molecule (in solid, liquid or gas) that have acquired an electric charge by gaining or losing one or more electrons.
JOULE
The unit of energy or work in physics. A force is developing a distance in the direction of al force acts and energy is spent. The unit are designated in memory of James Prescott Joule was the first to measure the relationship between heat and work in 1847 (1 calorie - 4.18 joules).
KILO
Prefix designating a thousand times the base unit (for example: 1 kV (1kV) = 1 000 volts).
WAVELENGTH
Distance between two corresponding points on consecutive waves. WAVE Regular or periodic variations or pulses in space and / or time: their profile is the waveform (sine, square, sawtooth, in pulses).
OSCILLATION
The oscillation is a periodic variation. It may be the variation of a voltage (= voltage), a current (amperage =) or a mechanical vibration system (or its apparent car).
PERIOD
This is the time elapsed between two consecutive corresponding points on the shape of a wave. It is a reciprocal of the frequency.
PHASE
This parameter sets the position of a periodic phenomenon. He is represented by the fraction of a complete cycle, measured in angular degrees or radians (1 cycle = 360 °). Electricians wire designate as "phase" in an electrical installation, the wireless carrier voltage (versus over "neutral" which corresponds to zero potential).
