A circular loop of wire is in a region of spatially uniform magnetic field, as shown in the figure (Figure 1). The magnetic field is directed into the plane of the figure. Determine the direction of the induced current in the loop when b is increasing.
A single current-carrying circular loop of radius R is placed next to a long, straight wire, as shown in the sketch in Figure. The current in the wire points to the right and is of magnitude I. In which direction must current flow in the loop to produce zero magnetic field at its center?
A) Counterclockwise
B) Clockwise
C) It is indifferent if clockwise or counterclockwise.
D) The current in the loop should be zero A.
