A Wire Loop Is Bent Into The Shape Of A Square With Each Side Of Length 1 5 Cm The Loop Is Placed Horizontally On A Tab 1 (42.01 KiB) Viewed 16 times

A wire loop is bent into the shape of a square with each side of length 1.5 cm. The loop is placed horizontally on a tabletop with two of the sides oriented north/south and two of the sides oriented east/west. A battery is connected so that a current of 14 mA is produced around the loop; the current flows in the clockwise direction looking from the top. What is the force produced by the earth's magnetic field on each section of current-carrying wire? What is the overall torque on the loop? What would the torque be if the same length of wire were bent into a circle instead of a square (assuming the same current)? Two squares of wire like that in the previous question are placed side by side on a table with a distance of 3 cm between the closest sides of the two squares. A 15 mA current passes counterclockwise through both squares. What is the resulting force between the two squares? Is it attractive or repulsive? (20 Marks)
