Zero Magnetic Field Type Magnetic Field Sensor

open access: yesIEEJ Transactions on Electronics, Information and Systems, 1990
AbstractThis paper presents a new magnetic field sensor named the zero magnetic field type, on the basis of its principle of operation, which is as follows: when the magnetic field level in the core used as a sensor is shifted by an unknown field to be detected, a controlled field is so superimposed in the opposite direction to the unknown field that ...

A mathematical model and experimental procedure to analyze the cognitive effects of audio frequency magnetic fields

open access: yesFrontiers in Human Neuroscience, 2023
Audio frequency magnetic fields (20 Hz−20 kHz) are magnetic fields in extremely low frequency-very low frequency (ELF-VLF) bands that are present near audio equipment and acoustic transducers.

External Field-Controlled Ablation: Magnetic Fields [PDF]

open access: yesNanomaterials, 2019
Laser ablation of silicon under an external applied magnetic field with different orientations was investigated in respect to the scanning direction and polarisation of the laser beam, by observation of the ablation patterns and debris deposition. Ultra-short ∼230 fs laser pulses of 1030 nm wavelengths were used in the single and multi-pulse ...

Computer Adaptive Testing Using Upper-Confidence Bound Algorithm for Formative Assessment

open access: yesApplied Sciences, 2019
There is strong support for formative assessment inclusion in learning processes, with the main emphasis on corrective feedback for students. However, traditional testing and Computer Adaptive Testing can be problematic to implement in the classroom ...

Open Magnetic Fields in the Martian Magnetosphere Revealing Dipole-like Intrinsic Magnetic Fields at Mars

open access: yesThe Astrophysical Journal Letters, 2023
Mars’s magnetosphere is hybrid, having contributions from both an induced magnetosphere like Venus and the localized crustal magnetic fields. However, the planetary fields also include large-scale, more global components.
