PROBLEM TO BE SOLVED: To provide a demagnetization method capable of demagnetizing an object to be demagnetized, such as a tire or the like, simply and without upsizing an apparatus, and to provide the apparatus therefor. SOLUTION: The demagnetization method uses a magnetic field generating means 3 having a pole face 2 in which north poles and south poles are alternately disposed in a loop to demagnetize an object to be demagnetized 4. After the object to be demagnetized 4 is disposed to face the pole face 2, the pole face 2 and the object to be demagnetized 4 are gradually separated while they are relatively moved by rotating them in asynchronization with one another.
