An interesting use for Faraday Cage



Faraday Cages are used to cancel out electric fields and block most forms of electromagnetic radiation. And people in today's world have used this in some creative ways. Some people put their phones in these cages so that they can't receive any calls or texts. But I was reading and this article said that a shop lifter had be caught with a bag lined with aluminum foil. This created the bag a Faraday cage so that when the person put the item they were stealing in the bag, the bag blocked most of the signal from the tag that make the sensors by the doors of stores go off when someone tries to shoplift. However this person didn't manage to get a complete cage and the alarms went off. This is just a very different application of physics than we learn in class but it's still cool
