Abstract
(EN)
This magnetism detection device 1 comprises a transmission line 10 that has a wire-like first conductor 11 including a magnetic material, a signal generator 30 that applies a pulse to the transmission line 10 as an incident wave, and a calculation device 20 that detects the incident wave and a reflected wave produced by an impedance difference at a magnetic field application position on the transmission line 10. The calculation device 20 calculates the position and intensity of a magnetic field applied to the transmission line 10 on the basis of the incident wave and reflected wave.
