The long, straight wire in the figure has a current i = 1.07 Aflowing in it. A square loop with 10-cm sides and a resistance of0.0309 O is positioned 10 cm away from the wire. The loop is thenmoved in the positive x-direction with speed v = 15.09 cm/s.
a) Find the direction of the induced current in the loop. (Enter -1for clockwise, +1 for counterclockwise).
-1
b) Identify the directions of the magnetic forces acting on allsides of the square loop.
(You can enter x, -x, y, -y, z, -z, for each of the 4 sides. Thefirst answer is for the top part of the loop, the next for theright side, then the bottom, and finally the left side. Separatethe answers for each side by commas. Use no spaces. Example: If youthink that the force vectors on the top and bottom point in thenegative z-direction [=into the page], and the force vectors on theleft and right point in the positive y-direction, then enter:"-z,y,-z,y".)
y,x,-y,-x
c) Calculate the magnitude of the net force acting on the loop atthe instant it starts to move.
