B. Magnetometer networks

It's called a magnetometer.

International Heliophysical Year magnetometer observatories

Each proposed International Heliophysical Year magnetometer observatory will consist of magnetometer station pairs separated meridionally by approximately 200 km.

Stations of the Circum pan Pacific Magnetometer Network

MAGDAS CPMN magnetometer system for real time data acquisition

CARISMA is the magnetometer element of the Canadian GeoSpace Monitoring (CGSM) project.

Magnetometer arrays provide a relatively low cost method for monitoring solar terrestrial interaction.

Would you mind going to the storeroom upstairs and see if there's a magnetometer.

Magnetometer stations provide monitoring of current systems local to monitoring stations, as well as local wave populations.

The International Heliophysical Year magnetometer array could aid development in countries such as Ukraine where suitable expertise exists.

It is valuable to have a central International Heliophysical Year magnetometer array data centre to collect, store and archive the data.

The scientific value of the collective International Heliophysical Year array data set encourages collaboration between International Heliophysical Year magnetometer array scientists from participating countries.

You can make out a list for all the things you need, and I'll go and see if I can get a magnetometer for you.

Magnetometer observatories can be developed under the International Heliophysical Year United Nations Basic Space Science Initiative programme based on the achievements of the Canadian Array for Realtime Investigations of Magnetic Activity (CARISMA).

It is the continuation of the Canadian Auroral Network for the OPEN Program Unified Study (CANOPUS) magnetometer array, which ran from 1986 to 2005, with upgrading to include higher time resolution and more complete time coverage.

MAGDAS will utilize the Circum pan Pacific Magnetometer Network (see figure III) involving a number of countries around the globe (Australia, Indonesia, Japan, the Philippines, the Russian Federation, the United States and Taiwan Province of China).

This insight was made possible not only due to scientific magnetometer measurements of the era, but also as a result of a significant portion of the of telegraph lines then in service being significantly disrupted for many hours throughout the storm.
