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 50cm by 3cm .

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 50cm by 3cm . 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.
