摘要：A magnetic property determination apparatus that determines the magnetic materials on a paper sheet transported through a transport path includes a magnetization unit and a magnetic detection unit. The magnetization unit generates a magnetization magnetic field including a first magnetic field region and a second magnetic field region on the transport path. A magnetic field intensity and a magnetic field direction are set different between the first magnetic field region and the second magnetic field region so that the magnetic materials are magnetized in different magnetization directions depending on coercive forces of the magnetic materials. The magnetic detection unit that generates a bias magnetic field on the transport path downstream in a transport direction of the magnetization unit, and that detects a magnetic charge of the magnetic materials by detecting variations of the bias magnetic field.
