Modeling a sectored radial magnet with Magnum

In the tutorial Designing permanent-magnet solenoids with PerMag, I discussed how permanent magnets with radial magnetization could be used to generate a solenoid field. An annular magnet with pure radial magnetization is impossible to fabricate with modern high-energy-product materials. Instead, it must be approximated with a set of Ns wedge sectors, each with linear magnetization. There […]

Doing four things at once

People involved in technical work must often switch between different classes of tasks. For instance, when I am working on a report I may be running TeXnicCenter and Yap to do the writing, several of our finite-element programs to check data and to generate new results and FastStone and PaintShop Pro to create and to organize […]
