Tech Tips: Understanding the Different Kinds of Magnetic Properties 

December 19, 2022 Editorial Staff Comments Off on Tech Tips: Understanding the Different Kinds of Magnetic Properties 

Depending on how they interact with magnetic fields, most materials are classified as diamagnetic, paramagnetic, ferromagnetic, ferrimagnetic, or antiferromagnetic. We love the article by Mike Gedeon, customer technical services manager of Materion Performance Alloys and Composites, that explains these different kinds of magnetic properties and related aspects such as magnetic susceptibility. A few highlights follow. […]

Big Magnets Require Big Deliveries 

September 6, 2022 Editorial Staff Comments Off on Big Magnets Require Big Deliveries 

Some magnets are heavier than others. Handling them can be a challenge, in this case tackled by Wimmer Maschinentransporte of Germany. They can take longer to make, too. Two recent examples from the engineering and manufacturing facilities of Bilfinger Noell are the 13-ton monster PERC magnet shown, in part, above, and a superconducting “Wiggler” recently delivered to Brookhaven National Laboratory.  […]

Reduced-Helium Magnets from Philips a Game-Changer in MRI Scanners

August 18, 2021 Editorial Staff Comments Off on Reduced-Helium Magnets from Philips a Game-Changer in MRI Scanners

Maximizing image quality is a given in any new magnetic resonance imaging scanner. Delivering that capability to the maximum number of patients and doing it cost effectively, however, depends on optimizing workflows and maximizing scanner up-time. Many radiology departments are currently under extreme pressure to perform more MRI scans on more patients, not only due to the aging population but also to deal with the backlog of cases resulting from the Covid-19 pandemic.
