Unformatted text preview: falling loop? c) If you want to prevent the loop from falling, consider the following questions in the qualitative sense: Do you have to decrease or increase the Feld in time? Will you be able to hold the loop in equilibrium for an arbitrary amount of time? (Give reasons!) d) Now to the quantitative answer: Calculate the magnetic Feld B ( t ) which steadies the loop and indicate the range of validity for the solu-tion. 1 Problem 2: Self-inductance (Grith Problem 7.27, p. 316) 30 P Try to compute the self-inductance of the hairpin loop shown below. (Neglect the contribution from the ends; most of the ux comes from the long straight section.) Youll run into a snag that is characteristic of many self-inductance calculations. To get a deFnite answer, assume the wire has a tiny radius , and ignore any ux through the wire itself. 2...
