1. A specimen transport system that transports a specimen mounted on a specimen holder by sliding on a transport path by an interaction between a plurality of electromagnets and a magnetic body provided in the specimen holder, comprising:
a plurality of detection points each formed by one of the plurality of electromagnets and configured for detecting a position of the magnetic body;
a plurality of transport paths provided above the plurality of detection points so as to cover the plurality of detection points;
a current detection unit configured to detect a current value flowing through the plurality of electromagnets of each of the plurality of detection points; and
a calculation unit configured to calculate the position of the magnetic body based on the current value detected by the current detection unit,
wherein a detection range at a first detection point that is part of a first transport path is different from a detection range at a second detection point that is part of a second transport path different from the first transport path, among the plurality of transport paths, and
wherein a threshold for calculating the position of the magnetic body based on the current value detected by the current detection unit is different between the first detection point and the second detection point.
