The north pole of a magnet is pushed towards a stationary coil and the ammeter deflects to the right. The magnet is returned to its starting position. The coil is then moved towards the stationary magnet along the same line.
Which prediction is correct?
The ammeter deflects left because the moving object has changed.
The ammeter remains at zero because the magnet is stationary.
The ammeter deflects left because the coil approaches a north pole.
The ammeter deflects right because the relative motion is unchanged.
