  2. Pointing stick - Wikipedia

    en.wikipedia.org/wiki/Pointing_stick

    A pointing stick (or trackpoint, also referred to generically as a nub or nipple) is a small analog stick used as a pointing device typically mounted centrally in a computer keyboard. Like other pointing devices such as mice , touchpads or trackballs , operating system software translates manipulation of the device into movements of the pointer ...

    en.wikipedia.org/wiki/Radio_Magnetic_Indicator

    A radio magnetic indicator (RMI) is an alternate ADF display providing more information than a standard ADF. While the ADF shows relative angle of the transmitter with respect to the aircraft, an RMI display incorporates a compass card, actuated by the aircraft's compass system, and permits the operator to read the magnetic bearing to or from ...

  4. Magnetic particle inspection - Wikipedia

    en.wikipedia.org/wiki/Magnetic_particle_inspection

    Magnetic yoke is a hand-held device that induces a magnetic field between two poles. Common applications are for outdoor use, remote locations, and weld inspection . The drawback of magnetic yokes is that they only induce a magnetic field between the poles, so large-scale inspections using the device can be time-consuming.

  5. Magnetic field - Wikipedia

    en.wikipedia.org/wiki/Magnetic_field

    The magnetic field of larger magnets can be obtained by modeling them as a collection of a large number of small magnets called dipoles each having their own m. The magnetic field produced by the magnet then is the net magnetic field of these dipoles; any net force on the magnet is a result of adding up the forces on the individual dipoles.

  6. Attitude and heading reference system - Wikipedia

    en.wikipedia.org/wiki/Attitude_and_heading...

    With sensor fusion, drift from the gyroscopes integration is compensated for by reference vectors, namely gravity, and the Earth's magnetic field. [3] This results in a drift-free orientation, making an AHRS a more cost effective solution than conventional high-grade IMUs that only integrate gyroscopes and rely on a high bias stability of the ...

  7. Magnetic switchable device - Wikipedia

    en.wikipedia.org/wiki/Magnetic_switchable_device

    A magnetic switchable device (often called a magnetic base) is a magnetic fixture that uses one or more permanent magnets in a configuration that allows the external field to be turned on or off. They are used in many applications including optics , metalworking , lifting , and robotics, to attach items to metal surfaces in a secure but ...

  8. L-shell - Wikipedia

    en.wikipedia.org/wiki/L-shell

    Plot showing field lines (which, in three dimensions would describe "shells") for L-values 1.5, 2, 3, 4 and 5 using a dipole model of the Earth's magnetic field. The L-shell, L-value, or McIlwain L-parameter (after Carl E. McIlwain) is a parameter describing a particular set of planetary magnetic field lines.
