BIFILAR MAGNETOMETER Meaning and
Definition
-
A bifilar magnetometer is a scientific instrument used for measuring and studying magnetic fields. It consists of two parallel wires, or filaments, suspended in a horizontal plane and oriented in the north-south direction. These wires, made of a non-magnetic material such as silk or quartz, are connected at both ends forming a simple pendulum.
The purpose of a bifilar magnetometer is to detect and measure the strength and direction of magnetic fields. When a magnetic field is present, it exerts a force on the wires causing them to twist. By measuring the angle of twist, the strength of the magnetic field can be calculated. The magnitude of the force exerted on the wires depends on the current flowing through them and the intensity of the magnetic field.
Bifilar magnetometers are commonly used in geophysics and navigation to accurately determine the strength and direction of the Earth's magnetic field. They are also employed in laboratory experiments for studying magnetic materials and conducting various scientific research. The instrument is highly sensitive and capable of detecting very small changes in magnetic fields.
The bifilar magnetometer provides a practical and effective means of measuring and analyzing magnetic fields. Its design allows for accurate and precise measurements, making it an essential tool in many scientific and engineering applications.
Etymology of BIFILAR MAGNETOMETER
The word "bifilar magnetometer" is composed of two main parts: "bifilar" and "magnetometer".
1. Bifilar: The term "bifilar" is derived from the Latin words "bi-" meaning "two" and "filaris" meaning "thread" or "wire". In physics, it refers to a setup or device that involves two parallel wires. The "bifilar" part of the word reflects the structure of the magnetometer, which typically consists of two parallel wires.
2. Magnetometer: The term "magnetometer" is derived from the combination of two root words, "magneto-" derived from the Latin word "magnes" meaning "magnet", and "-meter" derived from the Greek word "metron" meaning "measure". A magnetometer is a scientific instrument used to measure the magnetic field strength or magnetic properties of materials.
