Question:
Figure shows two current segments. The lower segment carries current i1 = 0.40 A and includes a circular arc with radius 5.0 cm, angle 180?, and center point P. The upper segment carries current i2 = 2i1 and includes a circular arc with radius 4.0 cm, angle 120?, and the same center point P. What are the
(a) Magnitude and
(b) Direction of the net magnetic field B at P for the indicated current directions? What are the
(c) Magnitude and
(d) Direction of B if i1 is reversed?
