Table 7 The energy proportion of the effective detecting points of the total energy

Perturbation location	Distribution of efficient point	Efficient value energy ratio (%)
(0, 0, 0)	115°–245°	98.56
(− 75, 0, 0)	245°–275°	97.88
(75, 0, 0)	85°–115°	97.65
(0, − 75, 0)	0°, 95°–265°, 360°	89.7
(0, 75, 0)	170°–185°	98.11

The effective measuring region almost locate on the opposite side of drive coil. The semicircle detection area can receive 90 percent of total energy when the goal at five different places
