Page 5: Warnings [ Refer To This Section Before Operation Of Electromagnet ]
REFER TO WARNINGS BELOW BEFORE OPERATING ELECTROMAGNET 1 Personnel Safety The Model 5451 is a unshielded electromagnet. In operation the magnet fringing field can be in excess of 0.5mT(5G). This can cause malfunctioning of heart pacemakers and other medical implants. We recommend that the fringing field should be mapped and warning signs be placed outside the 0.5mT... -
Page 6: Installation
Model 5451 magnet is installed. It may be necessary to orient the Model 5451 axis to minimize the effects of external fields, to resite ac power sources or to install suitable magnetic shielding. -
Page 7: Electrical Circuit
50°C . Clean, cool (16°C - 20°C) water at 2 l/min and 1 bar (15 psid) should be used to cool the 5451 magnet. The cooling copper tubes are electrically isolated from the coils to avoid electrochemical corrosion. A 50 micron filter should be placed before the input to the magnet to trap particulates. - Page 8 Section 3 INSTALLATION Cooling - continued Freon, oil, ethylene glycol or other cooling mediums can be used. The flow required will be approximately inversely proportional to their specific heats. An experimental determination of the flow and pressure required will be necessary. Avoid cooling the magnet below the dew point of the ambient air.

Page 9: Operation
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. -
