An instrument for measuring the intensity of magnetic forces; also, less frequently, an instrument for determining any of the terrestrial magnetic elements, as the dip and declination.
An instrument used for measuring magnetic forces or for finding concealed metal.
an electronic device for detecting small anomalies in the earth's magnetic field. Can be used to explore certain subsurface characteristics of an archaeological site prior to excavation.
instrument that measures the strength and direction of magnetic forces.
An instrument that measures the magnitude (strength), and sometimes direction of a magnetic field.
An instrument that measures magnetic fields and sometimes the composition of the solar wind
An instrument used to measure the magnetic attraction of underlying rocks.
instrument designed to measure magnetic field strength and/ or direction
An instrument that measures the strength of the Earth's magnetic field.
an instrument used to measure the intensity and direction of a magnetic field, especially that of the earth.
Also known as a fluxgate gradiometer. A remote sensing instrument capable of identifying sub-surface archaeological features by measuring the difference in their magnetic properties against the surrounding soils
An instrument used to detect iron underwater; invented by Fay Field.
An instrument designed to measure the strength and character of Earth's magnetic field.
An instrument used to detect small changes in a planet's gravity to measure its magnetic field. The changes are measured in units of nanotesla.
device which compares the intensity and direction of magnetic fields.
an instrument that measures the amount of magnetism in a rock sample.
An instrument to measure magnetic fields.
an instrument for measuring the strength of a magnetic field
a meter to compare strengths of magnetic fields
a device that, like the magnet of a compass, reacts to changes in the earth's magnetic field
an instrument for measuring magnetic intensity, especially of earth's magnetic field, but also of many substances, chemicals and elements
an instrument for measuring the direction and/or intensity of magnetic fields
an instrument that can detect metal objects buried underground
a passive device that measures the strength of the local magnetic field
a scientific instrument used to measure the strength of magnetic field s
a solid state electronic device that can detect magnetic fields
a type of geophysical instrument used to measure the strength and direction
a very complex instrument which measures both the orientation and strength of a magnetic field
an instrument for measuring magnetic fields. Spacecraft often carry fluxgate magnetometers, which measure components of the magnetic field (3 of them are combined to give its strength and direction) but they need to be calibrated. Rubidium-vapor and similar instruments measure only the field strength, but their reading is absolute, related to atomic constants.
Instrument which is used to measure magnetic field strength in units of gamma.
Equipment that accurately measures the earth's magnetic field. Variations in the field can be due to different magnetic properties of different rocks. Interpretations can be made of the data recorded to give an indication of the structure of the rock strata.
A technical device used to study the strength, direction andfluctuation or magnetic fields.
Device for measuring magnetism.
Instrument that detects changes in the earth's magnetic field. Used by archaeologists to detect and map historic features and artifacts both in the ground and underwater.
a remote sensing device to detect differences in magnetism below ground and thus reveal probable features and materials
A device to measure the presence of a magnetic field as well as its strength, direction, and fluctuation. Paranormal researchers use the device in an attempt to detect a ghost' s magnetic or energy aura.
A proton magnetometer is a search tool detecting iron. More info.
General name for an instrument which measures the earth's magnetic field intensity.
An instrument that measures the earth's magnetic field and its changes. In ground prospecting, it usually measures the vertical intensity; in airborne prospecting, the total intensity
A device to measure the presence of magnetic fields as well as its strength, direction and fluctuation. Also called Electromagnetic Field Meter (EMF)
A device used to measure the magnetic fields in space and on the ground, and its changes. For example, a magnetometer can measure changes caused by solar storms.
A device to measure the strength of a magnetic field.
A scientific instrument used to detect disturbances and irregularities in the earth's magnetic field caused by the presence of metal, excavated areas, burned areas, or other disturbances in the soil. This helps archaeologists locate where people have previously lived and worked so they know where to excavate.
An instrument for measuring the magnitude and the direction of a magnetic field.
