SIMPLE MEASUREMENT

Measurement of fi nished products (magnets as actually used)

Flux meters are often used for measuring total fl ux and gauss meters are often used for measuring surface fl ux density. Calibration of search coils and hole probes is essential for these measurements. The following two methods are generally used for calibration.

  1. 1. Measure and select the best calibration.
  2. 2. Calibrate, using a high-accuracy standard sample. We recommend using a standard sample when setting magnetic characteristics.
Technical diagrams of magnetic measurement methods. The top panel shows 'Total Magnetic Flux (FLUX)' measurement using a Fluxmeter connected to a Coil, with a Sample attached to a nonmagnetic stick. The bottom panel illustrates 'Surface Magnetic Flux Density (Bd)' measurement using a Gauss Meter with a Probe and Hall Element Part placed against a Sample. These methods require precise calibration of search coils and Hall probes for accurate data
