33. 18 C 3 Turn on the power supply and increase the current until the desired field 15 reached Calibration The induction curves may be used to estimate the field in the air gap to within four or five percent More accurate field determination may be obtained by deriving experimentally a calibration curve for the particular pole and air gap combination being used Magnetic hysteresis in the yoke and poles can cause an error of 30 to 70G 3 to 7mT with an arbitrary application of such a calibration curve This effect may be reduced to less than one percent by following a prescribed current setting schedule designed to make the magnet forget its prior magnetic history The schedule should of course be used both in establishing the calibration curve and in its subsequent use A possible schedule would be From zero current increase to maximum current and reduce again to zero current Increase again to maximum current and reduce to the current to give the desired field setting Approaching the desired field from a higher setting will typically produce better field uniformity This 15 because the field changes at the pole edges will normally lag the field change at the center thereby helping to compensate the radial decrease in field Greater precision in setting up the calibration curve will be achieved with the use of a digital gaussmeter and by making a numerical table This table used with an interpolation routine will eliminate the error associ
