9.2.3.2 Detailed Design Procedure

For this particular case involving the TMAG5231B1DQDBZ, the user can arbitrarily start with a 1/8" × 1/8" × 1/16" magnet, a z-offset of 7 mm (>6 mm), and an initial displacement of one half of the magnet length (1/8"/2 = 1/16") and serendipitously get something that works (see Figure 9-12 and Figure 9-13). Had the B-field not exceeded BOPMAX, the user could try moving the magnet closer on the z-axis, made the magnet larger, or changed the magnet to one with higher permeability. Alternatively, if the b-field was too large, the magnet can be moved further away in each axis or a smaller magnet can be used.
