does the ferrite simply act as part of the magnet or would it dampen the magnetic field around the magnet some

Howdy...guitar pickup maker here, so I know a little about magnets, electromagnets, and inductors.
A two-pole magnet relies on the flux differential (magnetic strength) across its poles to generate the field around itself. What this means is anything that interferes with the flux anywhere in proximity of its mass will negatively affect the strength of the field near its poles.
Do you have magnetic viewing film? If not--get some. It's cheap and it allows you to visualize the field around a magnet. It's nowhere nearly as accurate as a gauss meter, but it will help you understand how different materials in proximity to a magnet affect the field.
