Homework Answers
When a conducting bar is place across the heavy wires as shown in the figure, the current would start flowing in clockwise direction (from positive terminal of battery to negative terminal of the battery) , thus the magnetic field created inside the loop will point in the direction of negative Z axis i.e. into the plane of paper .
Hence the magnetic field would increase.

The figure below pertains to questions 10.) and 11.). It
illustrates a 15cm long conducting bar resting on zero-resistance
wires. You begin exerting a force on the bar and thereby make it
move at constant speed. While the bar is moving, a counterclockwise
induced current is present in the conducting loop created by the
bar and wires.10.) Which of the following statements is false?a.) You are moving the conducting bar to the right.b.) The induced magnetic field through the center of...

In a region with a constant magnetic field as shown, there are
two conducting frictionless horizontal rails, a resistor and some
conducting wire along the left side and a conducting bar on the
right side that is free to slide left or right. The bar is
initially at rest but at time zero a force is applied to the bar
pulling it to the right so that the distance s increases with
time.
