magnetometer

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.

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.

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.

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.
