Brr? A circular loop of radius R is positioned in a region of BzR? magnetic field B (gray regions in the picture). What is the magnetic flux through the loop? Br(r? R?) Bn(R? - r?) As the right end of the loop has still to enter the region with magnetic field B (gray region in the picture), while the left end of the loop is exiting the region with magnetic field B, the induced current in the loop is ... Q Z If we move the loop into the region with magnetic field B (gray region in the picture), the induced current in the loop is ... Q Q o = If we move the loop out of the region with magnetic field B (gray region in the picture), the induced current in the loopis ... = A circular loop of radius r is placed inside a circular region of radius R where the magnetic field B is absent. If the magnetic field B increases, the induced current in the loopis ... Q Q1la <
