Sorry to be unclear. Intended meaning:

For a given alloy, a bigger magnet means a stronger pull. Even so, the Ric Toaster magnets pull less than smaller generic A5 rods. This suggests they are Alnico II rods, the only other alloy besides A5 that saw major use in pickups, despite infrequent use of Alnico's 3, 6, 5/7, 7, 8, and 9.

Dang! My error! Big friggin' OOPS!

Substitute "FEET" for winds on that 2800 figure. Depending on the bobbin, the number of winds could range 2-3 times the actual footage. 5600 - 8400 winds sounds a lot more realistic than 2800.

As a sanity check, #42 single build wire would need about 4500 feet to hit Rickenbacker's 7.4k mark.
