Electromagnetic Theory, PHYS 441B Norbert L¨utkenhaus Due: Wednesday, 28. Jan 2009, 10:30 110 Points Assignment 2 Remark: All known results from situations in Electrostatics and Mag- netostatics can be used in without derivation in assignments and exams. Problem 1: Fields, Charges and Currents (Griffith Problem 7.34, 30 P page 327) Problem 2: Induction (Griffith Problem 7.50, page 337) 30 P Additional task: Explain the observation that the two voltages differ. Think yourself in the position of an experiomentalist with one voltmeter
