A changing magnetic field induces an electric field; this is how asynchronous motors work. Having been in the room with a patient undergoing TMS a couple dozen times, I can assure you that the electromagnet will induce a muscle twitch from the electric field it creates. What it doesn't do is cause a seizure, which is the typical desired result of ECT.
