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.
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.
With already six installations at customer sites worldwide, this unique 950 MHz magnet, which has only been delivered by Bruker, provides ideal capabilities for demanding multidimensional biological NMR applications, while at the same time requiring a relatively small footprint due to its small stray field.
There are inevitably stray fields within the "zero-field" gaps that give rise to unwanted Larmor precession around the local stray field direction.
The ultra-low magnetic stray field design opens up a whole new range of applications.
The multi-gap technology used to manufacture the devices reduces fringing flux and stray field emissions.
