Question:

A single current- carrying circular loop of radius R is placed next to a long, straight wire, as shown in FIGURE 22-63. The current in the wire points to the right and is of magnitude I.

(a) In which direction must current flow in the loop to produce zero magnetic field at its center? Explain.

(b) Calculate the magnitude of the current in part (a).
