2. Hall effect sensor - Wikipedia

   en.wikipedia.org/wiki/Hall_effect_sensor

   A radial magnetic field established by magnets on the thruster is used to trap electrons which then orbit and create an electric field due to the Hall effect. A large potential is established between the end of the thruster where neutral propellant is fed, and the part where electrons are produced; so, electrons trapped in the magnetic field ...

3. MEMS magnetic field sensor - Wikipedia

   en.wikipedia.org/wiki/MEMS_magnetic_field_sensor

   A MEMS magnetic field sensor is a small-scale microelectromechanical systems (MEMS) device for detecting and measuring magnetic fields (magnetometer). Many of these operate by detecting effects of the Lorentz force : a change in voltage or resonant frequency may be measured electronically, or a mechanical displacement may be measured optically.

4. Magnetometer - Wikipedia

   en.wikipedia.org/wiki/Magnetometer

   Magnetic fields are vector quantities characterized by both strength and direction. The strength of a magnetic field is measured in units of tesla in the SI units, and in gauss in the cgs system of units. 10,000 gauss are equal to one tesla. [1] Measurements of the Earth's magnetic field are often quoted in units of nanotesla (nT), also called ...

5. EMF measurement - Wikipedia

   en.wikipedia.org/wiki/EMF_measurement

   E-field projections on an orthogonal reference frame. Measurements of the EMF are obtained using an E-field sensor or H-field sensor which can be isotropic or mono-axial, active or passive. A mono-axial, omnidirectional probe is a device which senses the Electric (short dipole) or Magnetic field linearly polarized in a given direction.

   That field is called electric field.If the charge doesn't move. If the charge moves, thus realizing an electric current, especially in an electrically neutral conductor, that field is called magnetic. Electricity can be given a quality — a potential. And electricity has a substance-like property, the electric charge.

7. Attitude and heading reference system - Wikipedia

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

   An attitude and heading reference system (AHRS) consists of sensors on three axes that provide attitude information for aircraft, including roll, pitch, and yaw.These are sometimes referred to as MARG (Magnetic, Angular Rate, and Gravity) [1] sensors and consist of either solid-state or microelectromechanical systems (MEMS) gyroscopes, accelerometers and magnetometers.

9. Magnetic field - Wikipedia

   en.wikipedia.org/wiki/Magnetic_field

   The magnetic field of permanent magnets can be quite complicated, especially near the magnet. The magnetic field of a small [note 6] straight magnet is proportional to the magnet's strength (called its magnetic dipole moment m). The equations are non-trivial and depend on the distance from the magnet and the orientation of the magnet.
