11. Unpacking Instructions and Damage Inspection To unpack the electromagnet please use the following procedure 1 First remove all of the Hex Head Screws located at the lower edge of all the side panels of the Crate Top Cover 2 Gently rock the Crate Top Cover to work it loose from the shipping crate base 3 Use one person on each side of the shipping crate grip the side panels of the Crate Top Cover Lift Crate Top Cover high enough to clear top of electromagnet walk cover sideways to clear area and place on floor 4 Inspect the magnet to ensure that no damage has occurred to the magnet in shipment If damage 15 evident report the damage in detail to the shipper for claim and simultaneously notify GMW in case assessment of the damage must be made If no damage 15 found proceed with magnet unpacking installation With suitable lifting equipment eg 150kg 3306 minimum safe lifting rating lift magnet clear of the shipping crate TAKE CARE THAT NO SIDE LOADS ARE PUT ON THE MAGNET MOUNTING LEGS OR DAMAGE MAY OCCUR Siting Considerations The Model 5451 has no magnetic shielding Magnetic material in the vicinity of the magnet will modify the magnitude and uniformity of the central region magnetic field As a general rule avoid magnetic material closer than approximately 1 meter of the central region Background fields such as the geomagnetic field and alternating field from 60Hz power sources are unshielded by the magnet
12. inlet temperature of approximately 18 C 2 Turn on the power supply and increase the current until the desired field 1s reached Calibration The Calibration factor may be used to estimate the field 1n the air gap to within one percent More accurate field determination may be obtained by deriving experimentally a calibration curve 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 associated with reading a graph In any event three points need to be remembered 1 A calibration curve or table 15 only as good as the precision employed in generating it 2 The field 15 defined only at the point it is measured It will generally be different at a different point m the magnet For example the induction curves refer to the field on the axis and at the center of the coil pair 3 The field is most directly a function of the current in the magnet coils Voltage across the coils 15 not a good measure of field since the electrical resistance of the coils depends on the temperature about 0 496 per degree Celsius Field Control Operation The necessity to use calibration curves can be avoided by using a field controller to sense the magnetic field and provide a corresponding power supply control signal through the power supply programming inputs Contact GMW for suitable instrumentation
