What is the maximum number of times a person can pass through the magnetometer?

• A. 1 time
• B. 3 times
• C. 4 times
• D. 2 times

Answer: (D)

When a magnetometer is used for screening, the process is designed to be efficient while allowing a brief second chance to clear any alarms. A person typically goes through once; if the alarm sounds, they are allowed to step out, remove or adjust items that might be triggering it, and then re-enter for a second pass. That second pass is the last allowed pass in this screening flow before escalation to secondary screening if the alarm continues. So the maximum number of times a person can pass through the magnetometer is two.
