Magnetically hard object and method for adjusting the direction and position of a magnetic vector

Abstract

The invention relates to a hard magnetic object and a method for adjusting a magnetic vector of a hard magnetic object. Therefore, the invention has the object, to provide a hard magnetic object and a method for its manufacture, which hard magnetic object has, without being influenced by an outside magnetic circuit, a desired resultant magnetic vector, which is in the frame of a predetermined tolerance range, and furthermore, that the hard magnetic object has a higher maximal energy density compared to the State of Art. According to the invention a hard magnetic object, which magnetic vector is as far as possible within the frame of a predetermined tolerance range, consists at least of one hard magnetic moulding ( 1 ) and at least one further moulded element ( 11 ), which are combined with each other in such a way, that by means of shape, bringing together and aligning of the moulding ( 1 ) and of the moulded element ( 11 ), a predetermined direction and position of the magnetic vector of the hard magnetic object is achieved. The magnetic vector of the hard magnetic object is the resultant magnetic vector of the magnetic vectors ( 4, 14 ) of the hard magnetic moulding ( 1 ) and of the moulded elements ( 11 ).
