A conductive rectangular loop is being pulled at constant speed v out of a region of uniform magnetic field that is going into the page as shown in the image. What is the direction of the induced current in the loop when half of the area of the loop is still in the field?
In each case the magnetic fields B are changing with the time and pass through the loop shown, clearly draw the direction of the current induced on the loops:
If the current in the primary solenoid is clockwise (looking at the front view), then find the direction of the induced current in the secondary solenoid (either clockwise or counterclockwise)?
