In automatic doors, an electromagnet is used to create a magnetic field that attracts or repels a metal plate on the door. When an electrical current is applied to the electromagnet, it generates a magnetic force that moves the metal plate, allowing the door to open or close automatically. This process is controlled by sensors that detect movement, ensuring the door operates efficiently.
