DX-2012AM Magnetic Moment and Magnetic Declination Measurement System
Hard Magnetic Materials Measurement
Three-dimensional Helmholtz coil and three-component fluxmeter for measuring magnetic moment and magnetic declination of permanent magnet materials.

Product Overview
DX-2012AM Magnetic Moment and Magnetic Declination Measurement System is designed for measuring the magnetic moment and magnetic declination angle of permanent magnets. The system determines magnetic parameters by measuring the magnetic flux components using a Helmholtz coil system and a multi-channel fluxmeter.
By placing the magnet sample on the test platform, the instrument measures the magnetic flux components and calculates the total magnetic moment and the magnetic field deviation angle along the main axis. The system can display values including total magnetic moment M, magnetic declination α, and flux components Øx, Øy and Øz.
This system is widely used for magnetic quality inspection of permanent magnets and magnetic component testing.
Key Features
- Accurate measurement of magnetic moment and magnetic declination angle
- Three-axis Helmholtz coil system for multi-directional magnetic analysis
- Built-in three-channel fluxmeter for simultaneous measurement
- Real-time display of magnetic flux components Øx, Øy and Øz
- High-resolution LCD display interface
- Computer-based data recording and reporting system
- Suitable for permanent magnet testing and quality control
