The presented technological procedure makes it possible to assemble large magnetic blocks from permanent magnets with a high value of maximum energy product in such a way that the individual magnets or magnetic plates are moved toward each other at a controlled speed in the direction perpendicular to the future common contact surface of these magnets, i.e. parallel to the induction lines crossing this contact surface. Unlike in the previously used way of assembling the blocks, it is thus possible to eliminate the influence of partial demagnetization as the blocks are being assembled and consequently to reach higher values of magnetic induction in the air gap of the magnetic circuit. When applying the new method of assembling the blocks for instance in circuits of magnetic filters for the purification of ceramic suspensions, a prerequisite for the further improvement of the technological parameters of filtration is thus created., Václav Žežulka and Pavel Straka., and Obsahuje bibliografické odkazy
The article provides the results acquired during the development of a magnetic circuit equipped with magnetic blocks assembled from NdFeB magnets with gradually increasing height. It presents the knowledge from the application of the new method of assembling these blocks and the achieved values of maximum magnetic induction in dependence on the distance from the surface of the blocks both for their different heights and for the different designs of the magnetic circuit in comparison with the values obtained for similar magnetic circuits with ferrite magnets., Václav Žežulka., and Obsahuje bibliografii
