An infinitely long wire carrying a 25-A current in the positive x-direction is placed along the x-axis in the vicinity of a 20-turn circular loop located in the x-y plane (see figure below). If the magnetic field at the center of the loop is zero, what is the direction and magnitude of the current flowing in the loop? Im d= 2 m Fig. P2: Circular loop next to a linear curent
