SM Magnetics Develops 2+ Tesla Permanent Magnet Assembly

By: George Mizzell, VP, R&D and Engineering

We often get asked to produce magnet assemblies that challenge the outer limits of possibilities, or the laws of physics.  Our ability to think creatively, along with a solution-mentality, has allowed us to achieve more then our customers can imagine, and even surprise us at times.

Our R&D Medical Challenge

SM Magnetics was challenged to develop a permanent magnet assembly that could achieve over 2 Telsa within a specific area.  After several simulations of designs, we were able to develop our own 2.2 Tesla Permanent Magnet Assembly.  This assembly was immediately purchased for a Research and Development application in the medical industry.  The design included a 5 mm sq. area that is 10 mm high with a magnetic field > 2 Tesla.

Future High Tesla Field Challenges

We are currently working on 3 additional High Field Permanent Magnet designs with magnetic fields of > 2T over 14” area, 3+ Tesla field in a 10 mm square area, and a request for a 4+ Tesla field in a large area.  We continue to push the magnetic materials and designs to meet these requirements.

Each of these assemblies will have a specific purpose based upon our customer’s application.  There are many applications that can use strong magnetic fields without the expense related to an electromagnet.   We continue to receive requests for high field permanent magnet assemblies, and our design and engineering team continue to research new methods and materials.  

As we introduce new findings and assemblies, we will also continue to work with advanced materials and assemblies to push the limits of magnetic fields.
