  1. Magnetic Fields of an Electric Guitar Pickup A Finite Element Analysis ( FEA ) using flexPDE Craig E. Nelson - Consultant Engineer

  2. Purpose of the Numerical Experiment: The purpose of this numerical experiment is to learn something about the magnetic fields in and around a guitar string magnetic pickup coil.

  3. Steel Guitar String Coil Wound Around a Iron Core Creates an Electromagnet Line of Symmetry Vector Plot of the Magnetic Field Intensity – the H field

  4. Steel Guitar String Coil Wound Around a Iron Core Creates an Electromagnet Line of Symmetry Normalized Vector Plot of the Magnetic Field Intensity – the H field

  5. Steel Guitar String Coil Wound Around a Iron Core Creates an Electromagnet Line of Symmetry Vector Plot of the Magnetic Flux Density – the B field

  6. Steel Guitar String Coil Wound Around a Iron Core Creates an Electromagnet Line of Symmetry Normalized Vector Plot of the Magnetic Flux Density – the B field

  7. Steel Guitar String Coil Wound Around a Iron Core Creates an Electromagnet Line of Symmetry Log Plot of the Magnitude of the Magnetic Flux Density – the B field

  8. Magnitude of the Magnetic Flux Density on the System Center Line – the B field

  9. Various Model Parameters

  10. Summary and Conclusions A finite element model has been developed that allows insight into the nature and magnitude of magnetic fields in and around a guitar pickup sensor. The model could be developed in many further ways.
