Gravitomagnetic acceleration of spinning disk

Greetings,

Here's my attempt to calculate the gravitomagnetic acceleration of a spinning disk and it's based on solution 2 here:
http://pleclair.ua.edu/ph126/Homework/HW5_SOLN.pdf



Converting the vacuum permittivity:



Converting a magnetic field to a gravitomagnetic field:



Converting to an acceleration:



So for a disk of radius 0.15 m spinning at 12k RPM we'll have the following acceleration vs distance:



So I would like to know if I got this right.


Regards.
