An Eel by the Tail

Mr. Tedder wanted to give his class a good show. So, with more feeling for dramatic effect than for scientific good sense, he'd wound the three solenoids with heavy insulated silver wire rather than with the light copper wire Ziegler had reported using. On the theory that, if he were to demonstrate the Ziegler effect it would be best to demonstrate a whole lot of it, Mr. Tedder contrived a battery of the new lithium-reaction cells. The direct current from this powerful battery was transformed by an antique, but workable, automotive spark coil.
