Active magnetic shielding with a magnetic field sensor

INTERMAG Asia 2005. Digests of the IEEE International Magnetics Conference, 2005., 2005
The shielding effect of a high-sensitivity magnetic field sensor and reverse excitation Helmholtz coil on the unidirectional noise magnetic field component was discussed in this paper. Results indicate that when the Helmholtz coil is small (about the same size as the sensor), a noise magnetic field of 60 Hz, 2.6 /spl times/ 10/sup -7/ T (p-p) can be ...

A magnetic field sensor and method of manufacturing a magnetic field sensor

1997
A method of manufacturing a magnetic field sensor having a stacked structure which comprises: a substrate (1); an exchange-biasing layer (2) comprising nickel oxide; a magnetic layer (3) which is exchange-biased with the exchange-biasing layer (2), whereby at least the exchange-biasing layer (2) is provided by sputter deposition using a sputter gas ...

Magnetic liquid sensor in orthogonal magnetic fields

Sensors and Actuators A: Physical, 1997
Abstract In this paper we present a sensor set-up based on magnetic liquids and provided for devices designed to measurement and control of physical parameters as: slope, displacement, acceleration, vibration parameters, value and direction of a magnetic field, etc. The sensor is under the influence of two crossed magnetic fields; one is a continuous

MAGNETIC FIELD SENSOR DESIGN

Sensor Review, 1991
The magnetic field generated or disturbed by an object is often overlooked when we need to inspect or detect it. In this tutorial Steve Macintyre describes the fundamental design principles of a range of magnetic field sensors.

Monolithic piezoresistive CMOS magnetic field sensors

Sensors and Actuators A: Physical, 2003
Abstract Two original electromechanical magnetic sensors have been developed using a fully industrial fabrication process that relies on bulk wet etching of CMOS dies. The first device uses the Lorentz force to actuate a U-shaped cantilever beam, while piezoresistive polysilicon gauges convert the beam bending into an electrical signal. A 2 μT sensor

Magnetic and Electric Field Sensors

2015
The main application for magnetic and electric field fiber optic sensors has been the electric power industry. The ability to dielectrically isolate equipment and personnel from high power provides an attractive feature in terms of safety and, ultimately, cost for fiber optic systems versus those using conventional technology.

Photonic Magnetic Field Sensor

2002
Abstract : Small, in-line polarization rotators or isolators to reduce feedback in fiber optic links can be the basis for excellent magnetic field sensors. Based on the giant magneto-optical (GMO) or Faraday effect in iron garnets, they with a magnetic field of a few hundred Gauss, (20 mT) for an interaction length for an optical beam of a few ...
