I'm currently in an engineering team trying to create a new device to find and mark on the surface where pipes are underground in construction sites.
We are trying to research the principles behind electromagnetic security tags as used in clothes and hardware stores. Could somebody tell me how they work?
Many thanks! My team are currently at Leicester De Montford university trying to put theirideas in to action so any help as quick as possible would be much appreciated.
