Magnetic Fields of an Electric Guitar Pickup

A Finite Element Analysis ( FEA ) using flexPDE

Craig E. Nelson - Consultant Engineer


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.


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


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


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


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


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



Various Model Parameters Line – the B field


Summary and Conclusions Line – the B field

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.
