Is there such a thing as a magnetic switch or sensor that would sense a magnet in the range of 12"-6" away?

There are devices called magnetometers for all kinds of magnetic sensing. Try a google search ....

They may or may not be suitable for your needs.

It depends on the strength of the magnetic field you want to detect. The simplest detector is a magnetic compass.

Depends on the power of the field your are trying to discover!

Magnetic field decreases at a rate of inverse cube of the distance (1/d^3). In other words the field strength knocks off pretty darn quick (of course this is dependent upon geometry and type of magnetic field). Here is an example calculation template you can use to see how the field of a permanent magnet degreades with distance.
