Metal detectors create a magnetic field by using a brief pulse of electrical current. The magnetic field will be reflected back to the machine if there are any metal objects present, such as a watch or a belt buckle. The return signal is detected by the machine and a beeping noise is produced to alert the TSA agent.

In the United States, the TSA will have to give the passenger a secondary screening if the alarm goes off. This is when an officer pats you down and uses a handheld detector. A secondary screening should only take a couple of minutes at most.
