Description
The hardware and software package allows an operator to generate an arbitrary magnetic field vector (Bx, By, and Bz) within the uniform space inside a 3-axis Helmholtz coil system. The magnetic field can be a stationary field pointing to any direction, or a linear/circular oscillating field. The operator can also generate any time dependence for the magnetic field. The package includes a 3-axis Helmholtz coil system, three independent power supplies, a computer, and controlling software. A 3-axis magnetic sensor measures the earth field accurately and the system is capable of canceling the earth field inside the 3-axis Helmholtz coil. The controlling software is easy to use, and all functions can be accessed and executed on the Graphics User Interface (GUI). This package is ideally suited to calibrate magnetic sensors and to measure field-dependent properties of materials. It can be used for research and development of biomedical devices, microscopy, magnetic nanoparticles, electronic compasses, MRAMs, MEMS, magnetic shape memory alloys, near-field sensors, micro- and nano-robotics.

The system can be custom made to meet each customer's requirements. Click here for information on a custom made Helmholtz coil system with controller for CubeSat calibration. 
Features
  • Triaxial Helmholtz coils with 7-9-11-inch diameter.
  • Maximum magnetic field 60, 50, 40 Gauss at DC.
  • Controller to generate three magnetic field components (+/-Bx, +/-By, and +/-Bz). The three field components can be either constants or sinusoidal.
  • Control Software for the operation of controller and Graphics User Interface (GUI). GUI will display direction/intensity/frequency of magnetic field. Users can specify the direction/intensity/frequency of magnetic field on the GUI. The control software with GUI can generate linear oscillating fields in any direction or rotational fields in x-y, y-z, or z-x planes.
  • Control Software can generate arbitrary time-sequenced magnetic fields.
  • Data acquisition channel for user to measure the output voltage (Vout) of UUT (Unit-under-Test). Standard: one channel. Multiple-channel option available.
  • Automatic generation of data file in spreadsheet format containing arrays of parameters: (1) time t, (2) Bx, (3) By, (4) Bz, and (5) Vout.
  • Computer and flat panel display.
  • 3-axis magnetic sensor for detecting local ambient earth field and automatic cancellation of local ambient earth field inside the Helmholtz Coils.
  • Electrical cables for Helmholtz Coils, 3-axis magnetic sensor, controller, and computer/display.
  • Manual of Operation.
Applications
  • Calibration of electronic compasses
  • Calibration of magnetic sensors
