Will aluminum foil go off in a metal detector
Aluminum was a METAL last I checked.
No. I frequently wear my aluminum foil hat when going through metal detectors because I cannot risk losing contact with the transmitter on JRP-998 in the Andromeda Galaxy. The hat never sets off the alarm. I do.
aluminum is undectable if you wrap your eay pass in it it wont register. i tried it. and a feriday cage wraped in tinfoil will block all signals to everything
The answer is Not Always. It depends on how much aluminum foil and also on the configuration of the aluminum foil (i.e. balled or flat). Most metal detectors operate by having two receivers with a central transmitter that both generates an electromagnetic field and broadcasts a radio frequency. Anything that enters into this field that is either Magnetic or Electrically Conductive will cause a disturbance in one or both of the field strengths. All metals will show one of these characteristics. However, aluminum foil can sometimes pass through, like in product packaging with aluminum foil lids and trays. But, please know that there are also Foil Detectors, that some places use, too.
