PART A:
Two long wires, one of which has a semicircular bend of radius R and center P, are positioned as shown below. If both wires carry a current, how far apart must their parallel sections be so that the total magnetic field at P is zero? Express a in terms of R. Does the current in the straight wire flow up or down? Explain.
PART B:
The infinite, straight wire shown below carries a current I1. The rectnangular loop, whose long sides are parallel to the wire, carries a current I2. What are the magnitude and direction of the total magnetic force on the rectangular loop due to the magnetic field of the long wire?
