Electromagnetic analysis of guitar pickup.

In transient analyses of electromagnetic fields with moving media, it is difficult to grasp the phenomena theoretically in the same manner of the convective heat diffusion since the treatment of the coupled problem with the field and dynamics must be necessary. In this presentation, we illustrate the dynamic magnetic flux patterns in the electric guitar pickup, where the string will move over the permanent magnet surrounded by the pickup coil, using COMSOL Multiphysics.
