A long, straight wire carrying a current of 3.00 A moves with aconstant speed v to the right. A 5-turn circular coil ofdiameter 1.25 cm, and resistance of 3.25 µΩ, lies stationary in thesame plane as the straight wire. At some initial time, the wire isat a distance
d = 19.5 cm
from the center of the coil. 4.55 s later, the wire is at adistance 2d from the center of the coil. What is themagnitude and direction of the average induced current in the coil?Note that while the magnetic field varies over the diameter of thecoil, it is very small and we will disregard this variation.
