The tire wear measurement device includes a first magnetic field detection portion placed at a position at which the magnetic field of the magnetic body can be detected, and a second magnetic field detection portion disposed at a position at which the intensity of the magnetic field of the magnetic body differs from the intensity at the position at which the first magnetic field detection portion is disposed.

Abstract: An arc detection system includes an obtainer and a determiner. The obtainer obtains a measurement result for current flowing in a power supply line to which power is supplied from a DC power source. The determiner determines, based on a component of a specific frequency band in the measurement result for the current obtained by the obtainer, whether an arc fault has occurred. The determiner determines that the arc fault has occurred when a specific time for which the component of the specific frequency band is at least a threshold is longer than an occurrence time in which an arc can occur when a device is attached to or detached from the power supply line.
