Could induction thaw ice?
Induction uses magnetic fields to move free electrons in a regular lattice (ie: a conductor). Ice doesn't have very many free electrons or a regular lattice, so no. It does have a few large ions and protons, but they are at least 1600X more massive, so they don't move much. In this YouTube video, iron filings are dispersed in ice in order to provide a conductive heat sink -- otherwise it would not heat.

An inductive heating device could be used to heat the pipe directly, though.

Something that could heat the ice directly is microwaves. I don't recommend it, however, as there wouldn't be much stopping the energy from bouncing around and heating you!
