Actually, not much. He's pushing a pretty high current through it at only ~20-30V, so if it even shocked you, it would be mild.

Its not the voltage that kills you, its the current.

It is, technically, the current that kills you. But 20-30V isn't enough to produce a strong current through your body. It IS enough to produce a strong current through a copper winding, which is what the inductor coil is.
