Patent ID: 8339009

Claim:
A magnetic flux conducting unit comprising: a pair of spaced apart magnetic flux conducting elements formed of a magnetically permeable material and defining at least one material receiving space; a magnetically permeable connecting portion connecting the pair of spaced apart magnetic flux conducting elements; wherein the pair of spaced apart magnetic flux conducting elements and the magnetically permeable connecting portion define a generally C-shaped element; respective magnets arranged relative to the spaced apart magnetic flux conducting elements such that magnetic attraction forces between the spaced apart magnetic flux conducting elements are reacted through and balanced within the magnetically permeable connecting portion; wherein a coil receiving space is defined between opposed faces of the respective magnets, receives a coil assembly of an electromagnetic apparatus, and is spaced apart from each of the material receiving spaces by a part of a spaced-apart magnetic flux conducting element of the pair of spaced-apart magnetic flux conducting elements; and wherein each of the at least one material receiving space accommodates a substantially magnetically impermeable material and is defined by at least two walls of a magnetic flux conducting element of the pair of spaced apart magnetic flux conducting elements, the at least two walls being disposed on a same side of the coil receiving space.
