Could I extend the range of a stud finder or magnetometer?

I'm looking to use it as almost a metal detector to find objects (without actually acquiring a metal detector). I know some programming but nothing about electromagnetic waves and wondering if there are any experts out there that might know more.

Can I make my iphone's magnetometer, for ex, work for up to 30 ft?
