  • Magnetic manipulation and navigation system for a magnetic element
    Patent number: 8830648
    Abstract: A magnetic manipulation and navigation system for moving a magnetic element through a body comprising at least six electromagnets fixed in relation to said body and a control unit supplying the current for the electromagnets. The electromagnets have soft magnetic cores and the current supplied by the control unit to each of the electromagnets is adapted to operate the electromagnetic coils of each of the electromagnets in their core's linear regions being delimited by the value of the flux density of each electromagnet being in an interval between the negative and positive saturation value of each electromagnet, the lower representation showing the deviation due to the use of soft magnetic cores in all electromagnets.
    Type: Grant
