A circular metal ring is situated above a long straight wire, as shown in the figure. The straight wire has a current flowing to the right, and the current is increasing in time at a constant rate. Show the direction of the magnetic field created by current I in the region near the loop and show the direction of the induced magnetic field in the loop. Which statement is true?

Consider a circular loop of wire. The magnetic field strength at the center of the loop is given by the equation B(t) = t, where t is time in seconds. If the induced electric field outside the loop is |E| = 3.4 V/m at a distance of r = 7.0 m from the center of the loop, find the radius R of the loop. Hint: The result of the line integral of the electric field around the path is E*2
