Permanent Magnet Mistakes, Part Six

Stan Trout, Spontaneous Materials

We continue with the sixth blog in this series, describing the many types of mistakes made with permanent magnets. Again, my intent is to help engineers in the future avoid mistakes made in the past, and not to embarrass anyone. Everyone’s experience is different, so please feel free to add your insights in the comments section below. Continue reading

Permanent Magnet Mistakes, Part Five

Stan Trout, Spontaneous Materials

We continue with the fifth blog in this series, describing the many types of mistakes made with permanent magnets. Again, my intent is to help engineers in the future avoid the mistakes made in the past, and not to embarrass anyone. Everyone’s experience is different, so please feel free to add your insights in the comments section below.

The fifth group of mistakes on my list are:

  1. Using the wrong adhesive
  2. Measuring the wrong parameters
  3. Failing to consider recycling in the design stage Continue reading

About The Magnetics Conference and Why I Love It

Thomas Schliesch, Head of Research & Development, Max Baermann GmbH

I have been attending the Magnetics conference since 2010 with one exception in 2013. I’d like to use this opportunity to give my estimate on why it has been worthwhile to visit regularly and why it will be in future. Continue reading

How to Assure Every Rare Earth (or Any) Magnet Meets Your Requirements 100 Percent of the Time

Dr John Ormerod, Principal, JOC LLC

So you have designed and thoroughly tested your revolutionary new magnetic device and are ready to place an order with your chosen magnet supplier. How do you assure the magnets you receive will meet your (and your customers) requirements 100 percent of the time? Continue reading

Permanent Magnet Mistakes, Part Three

By Stan Trout | Spontaneous Materials

We continue with the third blog in this series, describing the many types of mistakes made with permanent magnets. Again, my intent is to help engineers in the future avoid the mistakes made in the past, and not to embarrass anyone.

Everyone’s experience is different, so please feel free to add your insights in the comments section below.

The third group of mistakes on my list are:

  1. Believing that magnets do not require any special expertise to produce or use
  2. Designing a product with a non-existent material
  3. Assuming that cost is only from raw materials, or an easy to use $/kg figure, independent of quantity or complexity  Continue reading

How It Feels To Detect Simulation Errors

By Thomas Schliesch, Head of Research & Development | Max Baermann GmbH

Recently I took an old simulation of a magnetizing coil to apply it with a few modifications to a new magnet. This kind of simulation used a coupling between the coil itself and the feeding condenser discharge circuit, which was controlled by fairly long scripts for the FEM software. I had demonstrated that special coil together with the calculation of a related isotropic magnet as one subject of my presentation at the Magnetics 2012 conference [1]. Some of the results were also shown again at the Magnetics 2016 in another context. When flipping through the mentioned scripts to make the changes for the new magnet, suddenly something caught my eyes which made me get confused first, then later made me mad. Oh my! Continue reading
