Metals such as iron, nickel and cobalt are detected by passive and active metal detectors. Other metals, such as copper, brass and aluminum, are detected only by active means.
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.
