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?

The magnetic field around the head has been measured to be approximately 2.0×10−8 gauss . Although the currents that cause this field are quite complicated, we can get a rough estimate of their size by modeling them as a single circular current loop 14 cm (the width of a typical head) in diameter. What is the current needed to produce such a field at the center of the loop?
