Fluxgate Magnetometer

A fluxgate magnetometer is a precise device used to measure magnetic fields. It consists of a magnetic core with wires wrapped around it. When an external magnetic field is present, it affects the core's magnetism. By applying an alternating current through the wires, the device detects changes in the core's magnetization, allowing it to measure the strength and direction of the magnetic field. It's commonly used in geology, space exploration, and navigation to study Earth's magnetic properties and in various scientific research applications. Its accuracy makes it valuable for understanding magnetic phenomena.
