Chris,

I think the magnetic fields are indeed quite large but because of the
relatively large area that the fields spread over  the flux density (lines
per square centimeter) is  still relatively low. The earth's  natural
magnetic field represents this principle well. Also, I don't think too many
coilers are going to aproach their operating coils with ferrous metal
samples in their hands to try to "feel" the  pull of the magnetic field
generated by the primary/secondary coil. The first thing that that they'd
"feel" wouldn't likely be the magnetism ...  :^O
