The magnetic field has been measured to be horizontal everywhere along a rectangular path l = 15 cm long and h = 2 cm high, as in the following figure. 7 x 10-5 T -←个个 0.00011 T 0.00013 T E--- l --- Along the bottom, the average magnetic field B1 = 0.00013 T, along the sides the av- erage magnetic field B2 = 0.00011 T, and along the top the average magnetic field B3 = 7 x 10-5 T. Defining out of the page (toward you) as positive, determine the mag- nitude and direction of the current through this region. Remember that %3D µo = 47 × 10-7 T· m/A. Answer in units of A.

Along the bottom, the average magnetic
field B1 = 0.00013 T, along the sides the av-
erage magnetic field B2 = 0.00011 T, and
along the top the average magnetic field
B3 = 7 x 10-5 T. Defining out of the page
(toward you) as positive, determine the mag-
nitude and direction of the current through
this region. Remember that
µo = 47 × 10-7 T· m/A.
Answer in units of A.
