These effects are derived from two fundamental observations of physics: a steady current creates a steady magnetic field described by Oersted's law, and a time-varying magnetic field induces an electromotive force in nearby conductors, which is described by Faraday's law of induction.
Butter & salt. Preheat the oven to 400 degrees. Husk the corn, wrap each ear in foil, adding 2 teaspoons of butter to each packet. Bake for about 25 minutes or roast the foil-wrapped corn over hot coals turning once during the cooking. Serve with more butter and salt.
From Frozen. Preheat the conventional oven to 350 degrees Fahrenheit and place the number of corn dogs you'd like to eat on an ungreased cookie sheet. Place the cookie sheet on a rack in the center of the oven and bake for 18 minutes. Remove the cookie sheet and carefully touch the corn dogs.
