More News On Correlated Magnetics

14. January 2010

3 Comments

You may recall an article I wrote late last year on Correlated Magnetics Research, a company from Alabama who has created and produced what they were calling “programmable” magnets. Since then, I’ve had the chance to play with a number of their prototypes.  I had initially been a little confused as to what the technology […]

USA Reclaims World Record For Highest Field Resistive Electromagnet

The engineers and scientists at the National High Magnetic Field Laboratory [NHMFL] in Florida, announced this week that they had successfully tested a new resistive electromagnet that produces a magnetic field strength of 36 tesla (360 kilo-oersted), breaking the old record of 35 tesla (350 kilo-oersted) previously held jointly between the NHMFL and the Grenoble […]

New Downhole Permanent Magnet Generator Tool For Extreme Oil, Gas & Geothermal Drilling

Earlier today, my colleagues at Dexter Magnetic Technologies announced the launch of an innovative downhole generator tool, which we have developed for some pretty extreme drilling conditions. This new high pressure – high temperature (HPHT) tool could lead the way to drilling deeper and more productive oil, gas and geothermal wells in the world’s most demanding drilling environments. The tool […]

Vehicular Energy Storage Flywheel Concept Uses Permanent Magnet Gearing

Last week, a technical consulting company called Ricardo, based in the UK, issued a press release on its Kinergy concept for a “high-speed, hermetically-sealed flywheel energy storage system concept with a highly innovative and patented magnetic gearing and coupling mechanism“. What immediately drew my attention to the concept, is the use of a permanent magnet […]

Toyota Prius Vs. Tesla Roadster: The Results Are In (And Are Not What You’d Think)

So the day finally came.  DC permanent magnet motor vs. AC induction motor. Nickel metal hydride vs. Lithium-ion. Prius vs. Roadster… The place? Denmark… home of wind turbines, pickled herring and Kierkegaard. Not the first place you might expect the Prius and Roadster to come together, but the Fates must have had their reasons. Steen […]

Wind Turbines – Up Close And Personal

Last week I was in Denmark, and while there I had an opportunity to pay a visit to some wind turbines operated by Aalborg University in Northern Denmark.  Getting to finally see and hear a fully functional 2.3 MW wind turbine “in the flesh” was pretty cool, I have to say. There was a reasonable […]

Correlated Magnetics Research Launches “Programmable” Permanent Magnet Materials

I saw an intriguing news item over at the Magnetism & Electromagnetics Interest Group yesterday, and I see that it’s starting to make its way into the press.  The Huntsville Times is reporting that “Larry Fullerton, formerly of Time Domain, has developed a process to ‘program’ magnetic and electromagnetic materials so they will only attract […]
