A 1.5-volt battery is connected to a resistive wire whose resistance is 5 ohms. The wire is laid out in the form of a rectangle

50 cm by 3 centimeters (Figure 21.91). What are the approximate magnitude and direction of the magnetic force that the

upper part of the wire exerts on the lower part of the wire in the diagram? Explain briefly.
