  • Three Axis Equal Diameter Helmholtz Coil

Three Axis Equal Diameter Helmholtz Coil, 3 axis helmholtz coil, 3 axis Equal Helmholtz Coil

Three Axis Equal Diameter Helmholtz Coil Features:

1. Three dimensions are equal in the diameter of the coil, and the number of turns are same, coil constant also is in common.
2. Apply to the shielding room to shield cavity simulation field;
3. Suitable for constant wire coil requirements;
4. Suitable for 3 dimensional spatial homogeneity volume consistency of the application;
5. Applicable to the magnetic field under 2 gs requirements.
6. Three-dimensional equal diameter coil range: 100mm~1000mm

The Helmholtz coil refers to the arrangement of two identical conductor loops spaced one radius apart and wound, so that the current flows through both coils in the same direction. This winding generates an almost homogeneous magnetic field in the center of the structure with the primary component parallel to the axes of the two coils. Measurement of magnetic moment with a Helmholtz coil is a convenient way to test permanent magnet materials.
The Helmholtz coils can be single-axis (one coil pair) or 3-axes (three coil pairs at 90 degrees from each others). The triple-axes version lets you fully characterize the magnitude and the direction of the magnetization with respect to the axes, regardless of how you place the magnet. The complete measurement system consists of a 3-Axes Helmholtz coil set, a cabinet containing three fluxmeters and a PC. Detailed specs are listed in the following.

The measure can be done to every kind of hard magnetic materials having any different magnetization direction. This system was developed to be used with 3-axes Helmholtz coils, but it can also be used with any single-axis Helmholtz coil
