The SpinCoil series of Helmholtz coils are used to generate uniform magnetic field over certain volume in space. Each set of Helmholtz coils consists of two coils in a special arrangement to maximize the spatial volume of uniform magnetic field. The magnetic field generated is propositional to a DC or AC current into the coil. We provide a calibration curve between the field and the strength of DC current, called field-current calibration. We offer standard Helmholtz coils with different dimensions for generating single axis, two-axis, or three-axis magnetic field.

We can custom make the system based on your requirement. The 3-axis HHC system showed on this page can generate up to 1.6 G magnetic field, with uniform area of > 3 inches diameter sphere from coil center and vector change of less than 0.1 degree peak to peak. 


Quality Construction: SpinCoil series of Helmholtz coils use high quality insulating materials for the physical frame. The conducting wires are encapsulated in epoxy for mechanical stability. The physical package and the windings of the wires are manufactured for maximum field uniformity and stability.


Accurate Calibration: We design the Helmholtz coils� physical and electrical parameters based on the theory of electromagnetism. On top of this, we provide an accurate experimental calibration data for each set of Helmholtz coils. Calibration accuracy is 0.4%


Adaptive Platform Design: We provide a set of mounting holes for the sample holder platform in the uniform field region. Customer can also purchase sample holder platform which guarantees central alignment for measuring sample.


Easy Operation: Colored banana connectors on the stand of the Helmholtz coils are used to connect to the external power supply, with each color indicating the polarity of current direction, and hence, the field direction.


Multi-axis Magnetic Field Generation: The SpinCoil series are designed such that single, double, or triple sets of Helmholtz coils can be easily assembled together. As a result, you can generate magnetic field vectors in X, XY, or XYZ coordinates.


Customer centered services: We guarantee our products against defective parts and poor workmanship. In case your SpinCoil is under repair, we will provide you with a loaner, so that the disruption to your measurement is minimized.
The SpinCoil series of Helmholtz coils can be used for multiple purposes.
  • Calibration of magnetic sensors
  • Measurement of magnetoresistance of magnetic or spintronic devices
  • Measurement of Hall effect of magnetic or spintronic devices
  • Measurement of magnetic properties of materials (e.g., magnetic susceptibility)
  • Generation of magnetic field in a moderate to large spatial volume
  • Generation of static or dynamic (e.g., rotating) magnetic field vectors
  • Educational demonstration of magnetic field generation
  • Observation of interaction between magnetic field and magnets
  • Generation of zero field environment by canceling the earth's magnetic field
  • Confinement of plasma inside an evacuated container (e.g., a glass bulb)
  • Use for nuclear magnetic resonance experiment
