Chapter 5.2, Problem 3bT

Obtain a wire loop. The Loop represents the boundary of an imaginary flat surface of area A. (In order to allow the nails that represent the field to pass through the surface, you have only been given the boundary of the surface.)

Draw a diagram to show the relative orientation of the loop and the electric field so that the number of field lines that pass through the surface of the loop is:

• the maximum possible.

• the minimum possible.
