Research on the magnetic force of a blood pump driven by large gap external magnetic field

  The calculation model of the single turn rectangle current carrying coil was established.The theoretic formula for calculating the magnetic field intensity of any point in space was derived.For a pair of radial magnetizing permanent magnets,the formula for calculating the magnetic force of permanent magnet in the magnetic field was deduced based on the equivalent current theory of permanent magnet.According to the formula,the influencing factors and the changing rules for the magnetic force of permanent magnet can be seen directly:the current,the coil turns are proportional to its magnetic force,while the coupling distance is inversely proportional to its magnetic force.
