Geophysical survey (archaeology)
In archaeology, geophysical survey is ground-based physical sensing techniques used for archaeological imaging or mapping.
See Gradiometer and Geophysical survey (archaeology)
Gradient
In vector calculus, the gradient of a scalar-valued differentiable function f of several variables is the vector field (or vector-valued function) \nabla f whose value at a point p gives the direction and the rate of fastest increase.
Gravity gradiometry
Gravity gradiometry is the study of variations (''anomalies'') in the Earth's gravity field via measurements of the spatial gradient of gravitational acceleration.
See Gradiometer and Gravity gradiometry
Magnetic field
A magnetic field (sometimes called B-field) is a physical field that describes the magnetic influence on moving electric charges, electric currents, and magnetic materials.
See Gradiometer and Magnetic field
Magnetic flux
In physics, specifically electromagnetism, the magnetic flux through a surface is the surface integral of the normal component of the magnetic field B over that surface.
See Gradiometer and Magnetic flux
Magnetoencephalography
Magnetoencephalography (MEG) is a functional neuroimaging technique for mapping brain activity by recording magnetic fields produced by electrical currents occurring naturally in the brain, using very sensitive magnetometers.
See Gradiometer and Magnetoencephalography
Magnetometer
A magnetometer is a device that measures magnetic field or magnetic dipole moment. Gradiometer and magnetometer are Measuring instruments.
See Gradiometer and Magnetometer
Physical quantity
A physical quantity (or simply quantity) is a property of a material or system that can be quantified by measurement.
