Attractive Force Data
See Determining Thrust Force on page 321 for more information about calculating attractive
force. The data that is provided in Table A-3 shows the attractive force between the QSHT
motors and a high flux magnet array. This data is graphed in Figure A-4 , which shows how the
attractive force increases with an increase in the number of magnet array cycles.
