Currently Available Tests

Numbers given in this section are either manufacturers values taken from product manuals, or average values from previous test setups, actual accuracy and precision will vary for your specific setup.



• Stretched wire

• Precision: ~10^-4
• Accuracy: ~10^-4
• Potential Uses The stretched wire can be used in situations where you need a single measurement of the integrated strength of a magnet, or if you would like to see the length integrated strength of a magnet vs. the X position across the pole.
• Range: >.05T



• Long rotating Coil

• Precision:~10^-5
• Accuracy: ~5*10^-4
• Potential Uses Used in situations where high precision comparisons of integrated strengths are necesarry, large numbers of currents or magnets, or precision measuring of harmonics.
