Falling Magnet Experiment
Two hollow tubes, one made of glass and the other made of aluminum, are
positioned vertically. A student holds identical cylindrical magnets against the
outside of the tubes and observe that neither tube attracts a magnet. Based on
this observation, the student predicts that each magnet will fall through its
respective tube with an acceleration of 9.81 m/s2. The student and his lab
partner then drop the magnets into the tubes from rest at position A, as shown
Position A Glass tube
conductor Position B The students make the following observations:
The magnets do not touch the sides of the tubes as they fall. The time for the...
