In an ATM, magnets are primarily used in the card reader to detect the magnetic stripe on a debit or credit card. When a card is swiped, the magnetic stripe, which contains encoded information, passes through a magnetic field created by the reader. The reader then interprets the variations in the magnetic field caused by the stripe's data, allowing the machine to authenticate the card and process transactions. Additionally, magnets may be used in internal components, such as motors and sensors, to facilitate the operation of the ATM.
