Fluxgate Magnetometer Earth Field Sensor very simple gaussmeter

This video clip shows an extremely simple fluxgate design, ideal for the hobbyist or thinkerer. It needs not more than 1minute to be build, and the material needed is marginal. It is not so sensitive then a professional Sensor and also has drawbacks in stability and temperature sensitivity, but this is not a problem for the starting experimenter. Other simple magnetometer (gaussmeter) design have been already shown at YT but the sensitivity is most worse. Hope you have fun with the simple idea and get success by copy the simple and small sensor. ;)
