- Confusing it with a magnetometer (which measures field strength, not its gradient).
FAQ
Frequently Asked Questions
No. A magnetometer measures the strength of a magnetic field. A gradiometer measures the gradient (spatial rate of change) of the field. A gradiometer often uses multiple magnetometers.
In geophysical exploration (oil, minerals), archaeology, unexploded ordnance (UXO) detection, and in navigation systems for submarines and spacecraft.
Yes. Gravity gradiometers measure variations in the gravitational field and are used in geological mapping and for detecting underground cavities or dense mineral deposits.
No, it is a highly specialised technical term. The average native speaker is unlikely to know it unless they work in a relevant scientific or engineering field.
