The wire is supported inside the glass tube A with its upper pole at the same height as the magnetometer needle.
Or the magnetometer we use to keep a check on Earth's magnetic field.
The magnetometer recording showed that a very large mass of magnetic material lay on the ocean bottom, fifty fathoms down.
The magnetisation, or the molecular effect, is measured by the deflection of the magnetometer.
We find him also comparing magnets by what is known to us as the "magnetometer method."
One of the losses was a heavy case which formed the packing of part 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.
He'd helped plan and carry out the destruction of that warship because its existence and location were verified by a magnetometer.
When making the deflection experiment the magnetometer is arranged as shown in fig. 2.
This demagnetisation he detected by means of the movement of the needle of a magnetometer placed near one end of the iron wire.
An instrument for measuring the magnitude and direction of a magnetic field. Magnetometers are often used in archaeological and geological investigations to determine the intensity and direction of the Earth's magnetic field at various times in the past by examining the strength and direction of magnetization of ferromagnetic materials in different geological strata.
