T D 4 7. (25 pts) A wire loop of radius R-2.00 cm is next to a very long straight wire with the loop's center a distance D=5.00 cm from the long wire. In the loop a current 1-12.0 A is flowing clock-wise as shown. a. If the magnetic field at the center of the wire loop is zero, what is the magnitude and direction of the current I, in the long straight wire? b. If the current in the long wire is reversed (same magnitude, I.), what is the magnetic field strength at the center of the loop?
