Whats A Magnetometer Anyway?
OK, so there are magnetic flux waves all around us. In fact, way above us, the magnetosphere envelopes the earth, extending from about one hundred to several thousand kilometers above the surface, in which charged particles are trapped and their behavior is dominated by the earth’s magnetic field. The magnetic flux lines are really powerful. Anyway, a magnetometer is simply an instrument that measures the strength (and direction) of a magnetic field. Magnetometers are used to measure variations in the earth’s magnetic field for many reasons, including locating mineral deposits, buried treasure, submerged objects such as shipwrecks and now cars in your driveway. The earth’s magnetic flux lines are distorted when a large metal object like a car passes through them. (There’s even enough metal in my plastic Corvette to distort the flux lines.) This happens continually as you drive down the highway, and luckily for us, happens as anyone drives down your driveway. So, what does all this mean
