The superconducting magnet of the nmr spectrometer should have a magnetic field strength of about 9.4 t with an active shielding of the stray field. The hole should be of the type wide-bore with a diameter over 80 mm.
The stray field at the center of the 8-G model structure increases with rising values of [[??].sub.0], due to the small distances between the misaligned grains.
Another key advantage is that with a stray field of a few centimetres, the scanner can be placed near other scanners and sensitive equipment and does not require its own room.
Additionally a differential layout of the planar coils in the sensor system suppresses influences due to DC components of the stray field. Whereas this measurement principle is sensitive against impact by external electric fields [??] which are existing in electrical machines also, with significant strengths.
In the paper already mentioned above (Marble, 2008), Marble derives a magnetization pattern leading to the strongest possible stray field at a remote point.
The pump features a reduced and improved vibration spectrum and reduced magnetic stray field, which makes it suitable for analytical applications such as electron microscopy and high-end mass spectrometry, according to the company.
the magnetic field was generated by a stray field of a solenoid equipped with a ferromagnetic core with clearance.
With minimum stray field, REO Unity delivers a neat and straightforward solution to power quality problems in compliance with the EMC Directive.
The design of the DXM Series reduces failure modes often found with plating and solder terminated wires and leads, and the multi-gap technology used to manufacture the device also reduces fringing flux and stray field emissions.
The recording head for perpendicular recording consists of a single pole inductive write head with a suitable flux return path designed for high efficiency, low stray field sensitivity and sharp field gradient capable of writing on perpendicular media with coercivities in excess of 5000 Oe.
Today's higher frequencies and the compact nature of designs are forcing engineers to take wave propagation and stray field effects into account in calculations which would previously have been carried out in circuit simulators.
