Electromagnets are used for fire doors by holding them open during normal operation and releasing them to close automatically in case of a fire alarm. The magnets are connected to the fire alarm system and are designed to deactivate when the alarm is triggered, allowing the doors to close and block the spread of fire and smoke.
