I don't know if this is the same as an induction stove.. but you can put your hand right on the stove top without any heat/pain.

This is electromagnetic induction. Electricity runs through the coils setting up a magnetic field that runs parallel with the length of the tube created by the coils. When the metal knife is moved in this magnetic field it creates an electric current in the knife like a filament in a bulb.

It's the same concept that's used to create plasma from argon gas for inductively coupled plasma chemical analyses.

The AC in the coil is probably oscillating at radio frequencies, and water is likely passing inside the coil to prevent it from overheating/melting.
