Flexible is often a Rogowski coil -> http://en.wikipedia.org/wiki/Rogowski_coil. (http://en.wikipedia.org/wiki/Rogowski_coil.) Clamp-on probes can be Rogowski as well but more often they are split-core current transformer (sometimes combined with a Hall sensor to boost low-frequency response). There are also solid-core current transformer types.

Define "normal" current probe.
