Hi Jon and welcome to the Phorum,
The pm are there to bring the vane back to the center position. The coil moves the vane to the left or right not both depending on which way the coil wires are connected to the hv.
The pm doesn't have to be a super strong one as it would be fighting against the power of the electromagnet in my estimation. There a level of balance between the two. I haven't had to fool with the pm's so far. If it's too weak the vane will wobble and won't settle down for a few seconds after tuning in a station.

When my pals were reading comic books
I was down in the basement in my dad's
workshop. Perusing his Sam's Photofoacts
Vol 1-50 admiring the old set and trying to
figure out what all those squiggly meant.

Now I think I've got!
