magnetometer
磁强计,磁力仪,磁强仪,磁力计
Definitions
- 1
- : an instrument for measuring the intensity of a magnetic field, especially the earth's magnetic field.
- : an instrument for detecting the presence of ferrous or magnetic materials, especially one used to detect concealed weapons at airports.
Examples
We then used an ultrasensitive superconducting magnetometer and a special carbon dioxide laser to rapidly heat those samples in a way that avoids altering their iron minerals.
Among these new technologies was a small, portable device known as a fluxgate magnetometer.
In a fluxgate magnetometer, instead of a spinning needle like in a compass, a bar of iron is wrapped in two coils of wire.
His magnetometer was deceptively simple, consisting of two bar magnets, one suspended in the air by a fiber and one placed a known distance away.
Another Republican lawmaker referred to the magnetometers as “atrocities,” according to the Washington Post.
But another method of detecting the position of a metallic mass is by the use of the magnetometer.
A is the upper end of a glass tube, half a metre or so in length, which is clamped in a vertical position behind the magnetometer.
The wire is supported inside the glass tube A with its upper pole at the same height as the magnetometer needle.
With a good unifilar magnetometer, at a fixed observatory distant from the magnetic poles, having a fixed mark of Charts.
The apparatus may even be employed for measuring magnetic forces, as it constitutes a very sensitive magnetometer.
