An optimized magnet for magnetic refrigeration [PDF]

Journal of Magnetism and Magnetic Materials, 2010
A magnet designed for use in a magnetic refrigeration device is presented. The magnet is designed by applying two general schemes for improving a magnet design to a concentric Halbach cylinder magnet design and dimensioning and segmenting this design in an optimum way followed by the construction of the actual magnet.
