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 below. Magnet Ma Position A Glass tube (electrical insulator) Aluminum tube (electrica 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...
