The magnetic field has been measured to be horizontal everywhere along a rectangular path x= 22 cm long and y= 4 cm high, shown in the figure. Along the bottom the average magnetic field B1= 1.3 × 10-4 tesla, along the sides the average magnetic field B2= 1 × 10-4 tesla, and along the top the average magnetic field B3= 0.4 ×10-4 tesla. What can you conclude about the electric currents in the area that is surrounded by the rectangular path?
