As the current increases toward its maximum value, the inductor produces an emf that opposes the increasing current.
Check Your Understanding When using Kirchhoff’s laws, you need to decide which loops to use and the direction of current flow through each loop. In analyzing the circuit in Example 10.7, the direction of current flow was chosen to be clockwise, from point a to point b. How would the results change if the direction of the current was chosen to be counterclockwise, from point b to point a?

Integrated Concepts Derive an expression for the current in a system like that in Figure 23.11, under the following conditions. The resistance between the rails is R, the rails and the moving red are identical in cross section A and have the same resistivity . The distance between the rails is l, and the rod moves at constant speed v perpendicular to the uniform field B. At time zero, the moving red is next to the resistance R.
