Free energy from power line While on a camping trip, you decide to get some free electric energy. A power line is 12 m above the ground and carries an alternating current. You place a 0.50 m x 3.0 m coil with 100 turns below the wire so it lies with the 3.0-m side on the ground. The coil is connected to a lightbulb. (a) Will the lightbulb glow? (b) Indicate in a drawing the orientation of the coil relative to the power line so that a maximum changing flux passes through the coil. (c) If the current in the power line decreases from 200 A to 0 A in 1/240 s, what is the average emf induced in the coil? [Hint: Determine the field produced by the long straight power line (see Chapter 17)]. Describe any assumptions that you make.
