Some pickup and control circuit modelling in new online youtube lecture series from Aaron Lanterman at Georgia Tech ...

This is primarily about the electrical circuit the pickup is connected to, and so the description of the pickup parameters is approximate.  One thing that might cause confusion: the pickup inductance is not proportional to the permeability of the cores.  This would be a good approximation only if the core was closed, like a toroid; then it would not be a pickup!  Actually, even if the relative permeability is thousands, the coil inductance with the core is only maybe a few times more than the equivalent air core coil.
