- 總體規格:
-
- The Model 5453 Helmholtz Coil Electromagnet is a single axis coil pair arranged in Helmholtz geometry to give a relatively large volume of high uniformity magnetic field. The shielded enclosure allows increased maximum field and limits fringe fields to very low compared to traditional "open" Helmholtz coil.
- Applications:
- Low field NMR & EPR Spectrometry
- Materials measurement
- Sensor testing, development and calibration
- Electronic sensitivity
- Biological affect
