Please wait for the animation to completely load.

A dragable conducting loop is to the right of a wire as shown in the animation (position is given in meters and time is given in seconds). The graph shows the voltage read by the voltmeter attached to the conducting loop. (The polarity is also shown: when the voltage is positive, it means the voltage is higher at the red terminal than at the blue one, so current flows from the red around the loop counterclockwise to the blue). In which direction is the current flowing in the long straight wire? Restart.
