The Physics Teacher, 2012
Earlier papers1–3 in this journal have described experiments on measuring the magnetic fields of current-carrying wires and permanent magnets using magnetic field probes of various kinds. This paper explains how to use an iPad and the free app MagnetMeter-3D Vector Magnetometer and Accelerometer4 (compass HD) to measure the magnetic fields.

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.

Magnetic liquid sensor in orthogonal magnetic fields
Sensors and Actuators A: Physical, 1997Abstract 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
