Question

Homework Problem 9.7 The figure to the right shows two con- ducting loops of wire. Loop 1 is connected to a battery through a resistor at time zero and has non-zero inductance. The normal to the surface bounded by the loop lies in the plane of the page. Af- ter the switch is closed, but before the current in Loop 1 reaches a steady state, what effect does Loop 1 have on Loop 2? 2 Select One of the Following: (a) Loop 2 is not affected by Loop 1. (b) Loop 2 is attracted to Loop 1. (c) Loop 2 is repelled by Loop 1. (d) Loop 2 is forced upward by Loop 1. (e) Loop 2 is forced downward by Loop 1.

Answer 1

current increases As the in loop ! Din be an clockwise in flux an ,, 2 mores so that direction there will innyewe Towards left in loop 2 the loop will induce em of and current it towards right decrease the in flux change Loop 2 be reppelled by hoof I opte on (4) t will => Ans. is
