1. Metal detector

   A metal detector is an electronic instrument which detects the presence of metal nearby. Metal detectors are useful for finding metal inclusions hidden within objects, or metal objects buried underground. They often consist of a handheld unit with a sensor probe which can be swept over the ground or other objects. If the sensor comes near a piece of metal this is indicated by a changing tone in earphones, or a needle moving on an indicator. Usually the device gives some indication of distance; the closer the metal is, the higher the tone in the earphone or the higher the needle goes. Another common type are stationary "walk through" metal detectors used for security screening at access points in prisons, courthouses, and airports to detect concealed metal weapons on a person's body. The simplest form of a metal detector consists of an oscillator producing an alternating current that passes through a coil producing an alternating magnetic field. If a piece of electrically conductive metal is close to the coil, eddy currents will be induced in the metal, and this produces a magnetic field of its own. If another coil is used to measure the magnetic field (acting as a magnetometer), the change in the magnetic field due to the metallic object can be detected. The first industrial metal detectors were developed in the 1960s and were used extensively for mineral prospecting and other industrial applications. Uses include detecting land mines, the detection of weapons such as knives and guns (especially in airport security), geophysical prospecting, archaeology and treasure hunting. Metal detectors are also used to detect foreign bodies in food, and in the construction industry to detect steel reinforcing bars in concrete and pipes and wires buried in walls and floors.

1. metal detector

   A metal detector is an electronic device designed to detect the presence of metal objects within a specified area. It emits electromagnetic waves or magnetic fields that get disturbed upon encountering metal, causing a change in signal that alerts the user. These devices are commonly used in security checks, archaeological explorations, mining, treasure hunting, and in the detection of hidden metal infrastructure in walls and underground.

1. Metal detector

   A metal detector is a device which responds to metal that may not be readily apparent. The simplest form of a metal detector consists of an oscillator producing an alternating current that passes through a coil producing an alternating magnetic field. If a piece of electrically conductive metal is close to the coil, eddy currents will be induced in the metal, and this produces a magnetic field of its own. If another coil is used to measure the magnetic field, the change in the magnetic field due to the metallic object can be detected. The first industrial metal detectors were developed in the 1960s and were used extensively for mining and other industrial applications. Uses include de-mining, the detection of weapons such as knives and guns, geophysical prospecting, archaeology and treasure hunting. Metal detectors are also used to detect foreign bodies in food, and in the construction industry to detect steel reinforcing bars in concrete and pipes and wires buried in walls and floors.

2. Curtis Sliwa:

   Knowing that many gang members go to schools, if for nothing more [than] to recruit and sell drugs, they're going to be able to resolve their disputes in the classrooms, in the lunchrooms, within the school buildings itself, because now they won't even fear… a pat-down or having to go put their backpack through a metal detector, this is not focusing on what the real problem is.

3. Lisa Farbstein:

   The passenger needs to remove the pet from a carry case and carry it through the walk-through metal detector or walk the pet through the metal detector on a leash. This is typical of how people travel with small dogs. In the case of a cat, if there is no leash, we strongly recommend that the passenger requests screening in a private screening room.
