The box showed up yesterday with some assorted parts from Robert. 3200 turns of wire and little rigging later I have some measurements of the same magnet structure (pole piece and front plate) with an alnico magnet vs. a field coil. Below are the results of the comparison according to my flux-meter.

what are the axes of the graph? flux strength vs. voltage applied to thecoil is my guess but . . . .
ReplyDeleteI was going to ask the same. Secondly, what does it mean?
ReplyDeleteFlux density Vs. Coil current. It basically shows how the field strength adjusts the flux in the gap. The permanent magnet flux is fixed and there for reference.
ReplyDeleteAnd what difference does it make to Sound?
