1. A moving coil tissue penetration device, comprising: a) a magnetic source that produces a magnetic field in a magnetically active region;b) a lancet configured to penetrate tissue and mechanically coupled to a translation substrate;c) a magnetic core mounted to the lancet;d) a sharpened member guide that serves as a stop for an iron core; ande) an electromagnetic driver includes a driver coil pack that is divided into a plurality of coils along a path of the lancet with direct current configured to be alternated to the coils to advance and retract the lancet; wherein the magnetic source comprises a driver coil pack having a plurality of axially adjacent magnetic coils with axial lumens in a coaxial configuration; and wherein at least one of the magnetic coils comprises a permanent magnet. 2. The tissue penetration device of claim 1, further comprising a feedback loop having a processor which is electrically coupled to an elongate electrical conductor of a cylindrical wire coil and configured to control the magnitude of the force on the translation substrate based on feedback from a position sensor. 3. The tissue penetration device of claim 2, wherein the processor is configured to control the magnetic force on the translation substrate so as to have the translation substrate and the lancet follow a predetermined tissue penetration profile. 4. The tissue penetration device of claim 1 wherein the magnetic source is comprised of a ferromagnetic material. 5. The tissue penetration device of claim 4 wherein the ferromagnetic material is iron. 6. The tissue penetration device of claim 1 wherein the magnetic source is comprised of a paramagnetic material. 7. The tissue penetration device of claim 1 wherein the magnetic source is comprised of a permanent magnet. 8. The tissue penetration device of claim 1 wherein the magnetic source comprises an elongate conductor coiled about the magnetically active region. 9. The tissue penetration device of claim 1 wherein the magnetic source comprises at least one coil of electrically conductive wire electrically coupled to a controllable source of electrical energy. 10. The tissue penetration device of claim 1 further comprising a processor which is electrically coupled to the magnetic source and configured to control the magnitude of the magnetic field in the magnetically active region based on a feedback loop from a position sensor. 11. The tissue penetration device of claim 10 wherein the position sensor comprises an optical encoder and an optical encoder flag secured to the magnetic source. 12. The tissue penetration device of claim 1 further comprising a drive coupler and an elongate coupler shaft with the magnetic source secured to a distal portion of the elongate coupler shaft and the drive coupler secured to a distal end of the elongate coupler shaft. 13. The tissue penetration device of claim 1 wherein the position of the sharpened member guide is determined by measuring the position of the magnetic source.
