    Magnetic dip - Wikipedia

    Magnetic dip results from the tendency of a magnet to align itself with lines of magnetic field. As the Earth's magnetic field lines are not parallel to the surface, the north end of a compass needle will point downward in the northern hemisphere (positive dip) or upward in the southern hemisphere (negative dip). The magnetometer is detecting the iPhone! Fortunately, we can largely eliminate this effect by holding the iPhone in a constant orientation as we pass it over the suspected metal. As long as you don’t twist the iPhone as it is moved, the distortion of Earth’s magnetic field from the interaction of the iPhone does not change.

    The Dip Needle - Kenyon College

    The dip needle (or inclination compass) at the left was purchased from Ruhmkorff of Paris, probably in 1875, for Vanderbilt University. It is now on display in the Garland Collection of Classical Physics Apparatus at Vanderbilt. The concept of modern geological compass was developed by Eberhard Clar of the University of Vienna during his work as structural geologist. He published it in 1954. An advantage of his concept is that strike and dip is measured in one step, using the vertical circle for dip angle and the compass for the strike direction. Report on the Reconnaissance, Magnetometer Survey an the Bill and Cat Mineral Claims. Olivine buntoin, Tulameen, B. C.

    I'm currently developing an iPhone App (on iPhone 5, iOS 7, Xcode 5) which requires a very accurate determination of the current attitude. The "attitude" of CMDeviceMotion does not fulfil these requirements because Apple's sensor fusion algorithm seems to rely too much on the gyroscope which drifts away rather fast (in my experience). W S Darley Magnetic Dipping Needle Compass Magnetometer You are Bidding on a W S Darley Magnetic Dipping Needle Compass This is a Magnetic Dip Needle or sometimes also called a locating Compass that was actually used in the field and has since been in storage. sufficiently distant from the magnetometer, no calibration is necessary. This is not the case usually! •If ferrous object are close to the magnetometer an Hard-Iron calibration is necessary (rotation on the flat plane). •If SMT devices are close to magnetometer an Soft-Iron calibration is necessary (pitch, roll and yaw rotations).

    No. 2381: Magnetometer

    Every Boy Scout knows that the compass needle points north. The needle doesn't lie flat; it tends to dip north. The amount it dips and the direction it points reflect two components of the Earth's magnetic field. Magnetometers record the strength of those components. A magnetic needle suspended so as to be free to rotate about a horizontal axis. An instrument using such a needle to measure magnetic dip is called a DIP CIRCLE. A dip needle with a sliding weight that can be moved along one of its arms to balance the magnetic force is called a HEELING ADJUSTER.

    Thus the dip needle is not a magnetometer as ordinarily used. But, by taking two sets of readings, one may calculate from them the horizontal and vertical components of the magnetic field, and the dip needle becomes a horizontal and vertical magnetometer.

    If gravity is allowed to affect the needle’s performance then the effect of gravity will become a component of the measurement. This is the reason why magnetometers are used for measuring heading. The magnetometer is therefore an instrument for measuring both the strength and direction of magnetic fields. The classic magnetic-needle compass is not getting much respect or attention these days. Between the Global Positioning System (GPS) and the Inertial Measurement Unit (IMU) system, the compass – whether it is a traditional magnetic needle, or an electronic, no-moving-part version – seems like a redundant and unneeded navigation tool. magnetometer (mag-nĕ-tom -ĕ-ter) Any of a variety of instruments used to measure the strength and direction of a magnetic field.
