Consider a conducting loop placed on a horizontal plane in a region of uniform vertical magnetic field directed downward. If the magnitude of the magnetic field begins to decrease, what will be the direction of the induced current in the loop, as viewed from above? O Counterclockwise, so that the magnetic field of the loop is downward. O Counterclockwise, so that the magnetic field of the loop is upward. O Clockwise, so that the magnetic field of the loop is upward. O There will be no induced current, so that the loop does not have a magnetic moment. O Clockwise, so that the magnetic field of the loop is downward.
Question 1: When an external magnetic flux through a conducting loop decreases in magnitude, a current is induced in the loop that creates its own magnetic flux through the loop. How does that induced magnetic flux affect the total magnetic flux through the loop? O It does not affect the total magnetic flux. O It decreases and then increases the total magnetic flux. OIt increases the total magnetic flux. OIt increases and then decreases the total magnetic flux. O It decreases the total magnetic flux. Part (a) Some additional information, which is not included in the video, is that the SI unit of magnetic flux is the weber, denoted Wb.
