A rectangular loop of dimension and width moves with a constant velocity away from an infinitely long straight wire carrying a current in the plane of the loop as shown in the figure below. Let be the resistance of the loop. What is the current in the loop at the instant the near-side is at a distance from the wire? 
A current flows in an infinitely long wire along the axis of a hemisphere. The value of over the hemispherical surface as shown in the figure is: 
Consider two, single turn, co-planar, concentric coils of radii and with . The mutual inductance between the two coils is proportional to: 
A current flows in an infinitely long wire along the axis of a hemisphere. The value of over the hemispherical surface as shown in the figure is:
