GMW Dipole Electromagnet, 45mm, 3470
 |
| |
 The
3470 Electromagnet is the smallest and lightest
standard dipole electromagnet available from GMW.
It is used in a wide range of teaching, research and industrial
applications where a relatively small volume of field
is required. The light weight allows it to be used
on optical tables and the simple poles enable axial entry
& exit holes to be matched to the optical geometry.
Poles
The electromagnet has two 45mm (1 ¾ inch) diameter
cylindrical pole pieces. One end of each pole piece has
a plane cylindrical 40mm pole face and the other end has
a tapered 20mm pole face. The 40mm pole face produces
the most uniform field. The tapered 20mm pole faces are
used when higher gap fields are needed. Each pole piece
is clamped in the yoke by a bolt. The pole pieces are
adjusted to vary the gap by slackening the clamping bolts.
The same procedure is used to remove or reverse the pole
pieces. The gap is adjusted in the range from 0 to 75mm.
Optional square poles (50mm side) are available. (The
square poles have been applied in a simple mass spectrometer
as described in "Undergraduate Mass Spectrometer",
John W. Dewdey, American Journal of Physics, 28
(1960) 452-456.
Coils
The two coils are wound on spools, which have integral,
electrically isolated, water cooling tubes and overtemperature
interlock switches. Operation with water cooling allows
a maximum coil current of 5A. Regular tap water may be
used. Without water cooling, the maximum operating current
is 3.5A. The coil-to-coil spacing is adjustable over the
range from 35 to 75 mm.
