A position alignment method for position alignment between a position alignment apparatus including a reception pad and a magnetic field detection apparatus including a transmission pad which performs wireless power transfer (WPT) includes: connecting, by the position alignment apparatus, to the magnetic field detection apparatus using wireless communication, wherein at least one antenna is located in the transmission pad; radiating, by the position alignment apparatus, at least one magnetic field using at least one antenna located in the reception pad; receiving, by the position alignment apparatus, magnetic field measurement values from the magnetic field detection apparatus; and obtaining, by the position alignment apparatus, information indicating a positional difference between the reception pad and the transmission pad by comparing the magnetic field measurement values with previously-stored reference values.
