What is a magnetometer used for in correctional settings?

A magnetometer is a device specifically designed to detect metallic objects, making it particularly valuable in correctional settings. Its primary use is to scan individuals, their belongings, and various environments for weapons or other prohibited items. By utilizing magnetic fields, the magnetometer can identify the presence of metal, allowing correctional officers to prevent dangerous items from entering secure areas.

The effectiveness of a magnetometer in enhancing security cannot be overstated, as it serves as a primary line of defense against the smuggling of firearms, knives, or other weapons that could pose a threat to staff, inmates, or visitors. In contrast, other options such as performing a pat frisk, conducting an arrest, or interviewing suspects do not inherently rely on electronic detection devices. Those tasks are more hands-on and interpersonal, while the magnetometer provides a technological solution for detecting potential threats before they enter a facility.
