The sensor has two flux concentrators (3,4) and a sensor to measure a magnetic field. The flux concentrators (3,4) are separated by an air gap (5). Two Hall elements (1,2) serve as the sensor. The Hall elements (1,2) are arranged outside the air gap (5). At least some of ...
The Little Bee B1 is an open source magnetic field and current probe based on an Anisotropic Magneto-Resistive (AMR) magnetic sensor. It directly senses magnetic fields and measures current with a current sensing attachment consisting of a gapped ferrite toroid that is placed around a wire, estab...
In general, the relevant quality of such sensor probe is the minimum detectable current and the magnetic sensitivity. Both of these values are frequency dependent, and the former also depends on the spacing between current path and sensor tip. To maintain superconductivity, SQUIDs need to operate...
The current probe (1) includes a magnetic measurement element (2) that records temporal and local changes in the magnetic field induced by current flow in the conductor section (3). The magnetic field sensors, e.g. coil (10) and Hall sensor (11), of the measuring element are connected ...
Analysis of the optimal location of magnetic field probes for the determination of the current distribution inside S/C cables During the tests on superconducting cables, the magnetic field is often measured by means of pick-up or Hall probes and these data are used to reconstruct ... F Bellina...
These probes convert the voltage induced in an air core coil by the AC magnetic field that surrounds the current being measured. They have low impedance and lack the heat generation, saturation, and hysteresis caused by magnetic loss. AC zero-flux type current sensors These devices improve the ...
Magnetic field (11) sensor has a first Hall probe (13), with a first entrance and a first exit, which is so designed that the first Hall current flows in the first Hall current direction when a first input signal is applied to the first entrance. The first Hall probe supplies a first...

Calculations of AC magnetic losses from the experimental field profiles in various types of coated conductors under applied fields We measured the field profiles, H(x,Ha) s, near the surface of coated conductors (CCs) by using the scanning Hall probe method. The samples were SmBCO-CC t......
nonmagnetic and magnetic contributions to resistive switching signals in AFM/HM structures. This is particularly difficult for AFM/HM devices because, unlike FM/HM structures, magnetoresistance effects are typically smaller in AFMs, switching current densities are higher, and there is typically no ...
