A Magnetic Sensor with Amorphous Wire
نویسندگان
چکیده
Using a FeCoSiB amorphous wire and a coil wrapped around it, we have developed a sensitive magnetic sensor. When a 5 mm long amorphous wire with the diameter of 0.1 mm was used, the magnetic field noise spectrum of the sensor was about 30 pT/ÖHz above 30 Hz. To show the sensitivity and the spatial resolution, the magnetic field of a thousand Japanese yen was scanned with the magnetic sensor.

Magnetic sensors using amorphous metal materials: detection of premature ventricular magnetic waves
The detection of magnetic activity enables noncontact and noninvasive evaluation of electrical activity in humans. We review the detection of biomagnetic fields using amorphous metal wire-based magnetic sensors with the sensitivity of a pico-Tesla (pT) level. We measured magnetic fields close to the thoracic wall in a healthy subject sitting on a chair. The magnetic sensor head was mounted perp...
متن کاملGamma Irradiation Effect on Asymmetric Giant Magnetoimpedance of Co68.15Fe4.35Si12.5B15 Amorphous Alloy
The giant magneto impedance (GMI) effect is a large variation in the electrical impedance of a magnetic conductor when subjected to a static magnetic field. The sensitivity to the direction (AGMI) and magnitude of applied magnetic field and also linearity levels of this effect are three important parameters in magnetic sensors application. A suitable annealing procedure can be used to ac...

Magnetic field detection of biological electric activities would provide a non-invasive and aseptic estimate of the functional state of cellular organization, namely a syncytium constructed with cell-to-cell electric coupling. In this study, we investigated the properties of biomagnetic waves which occur spontaneously in gut musculature as a typical functional syncytium, by applying an amorphou...

The main magnetic characteristics regarding the domain structure and magnetization processes (axial, circular and Matteucci and inverse Wiedemann effects) of amorphous wires and glass-coated microwires are analysed. Magnetic bistability, spontaneously observed in samples with large enough ratio magneto-elastic anisotropy with axial easy axis to shape anisotropy, is the main source for a number ...

Tendency on miniaturization of the modern magnetic sensors and devices stimulates development of such magnetic materials with reduced dimensionality. Therefore magnetic materials with outstanding magnetic characteristics and reduced dimensionality recently gained much attention. Consequently thin wire with reduced geometrical dimensions (of order of 1-30 μm in diameter) gained importance within...
