the density of dots. Select true or false for the current in the loop. The cardinal directions are as defined in the compass rose. False

Fig 2: Loop moving North, induced current 'b'. False

Fig 1: Loop moving West, induced current 'b'. False

Fig 1: Magnet moving East, induced current 'a'. False

Fig 2: Loop moving East, induced current 'a'. True

Fig 2: Loop moving West, no induced current. False

Fig 1: Magnet moving West, induced current 'a'. First determine if the flux through the loop is increasing, decreasing or unchanged. (1) If the flux is increasing, then the induced current produces a field that is opposite in direction to the field by the existing magnetic field. (2) If the flux is decreasing, then the induced current produces a field that is in the same direction to the field by the existing magnetic field. (3) If the flux is not changing, then there is no induced current. Use the right hand rule (current and magnetic field) to determine the direction of the induced current.
