The standard observatory procedure for determining a geomagnetic field’s declination and inclination absolutely is the DI-flux measurement. The instrument consists of a non-magnetic theodolite equipped with a single-axis fluxgate magnetometer. Additionally, a scalar magnetometer is needed to provide all three components of the field. Using only 12 measurement steps, all systematic errors can be...

Introduction. In languages with fixed stress towards the left or right edge of the word, stress is often used for delimiting one edge of a prosodic phrase, while the other edge is marked by a boundary tone. In languages in which sequences between two accents form an accentual phrase (AP), the edge tones often show a regular pattern [2]. Both Hungarian and Slovak have stress on the left-most syl...

This research aims to identify the mineral rocks that are found in river village districts of Sumbermiri village, Lengkong district, Nganjuk regency. XRF tests have been conducted on a rock an result was 57 percent is calcite minerals. He method used geomagnetics, by measurig value total magnetic field area using magnetometer. Data collection done three times at each point, then retrieved data ...

The geomagnetic field at the earth’s surface changes over time, including in Indonesia. An accurate regional model is needed. Indonesia conducted just 49 repeat station measurements (out of 68) epoch 2020.0 due to COVID-19 pandemic. was modeled using collocated cokriging (CC) method, which proven be accurate. results show high accuracy with 1.18 minutes root mean square error (RMSE) for declina...

A new viewpoint on the generation and maintenance of the Earth’s magnetic field is put forward, which integrates self-exciting dynamo theory with the possibility of energy coupling along orthogonal axes provided by the Hall effect. A nonlinear third-order system is derived, with a fourth equation serving as an observer of unspecified geophysical processes which could result in field reversal. L...
