3470 Dipole, 45mm

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.

Applications

Hall Effect Studies
Magneto-Optical Studies
Laboratory Experiments
Magnetic Separation experiments
Magnetic alignment of small components
Studying chemical reaction rate changes

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 over-temperature interlock switches. Operation with water cooling allows a maximum coil current of 6A. 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.

Variation and Customizations

3470HFAC High Frequency AC Magnet. Fields to ±70mT with frequency from dc to 25kHz
3470-ET “Extended Throat” has a 165mm deep throat [from center of pole face to yoke cross-bar] sized to apply field to the center of a 300mm wafer.
Custom Yoke geometries (e.g. extended air-gap)
Custom poles optimized for field uniformity, physical access to sample, and optical access to sample.
