Unformatted text preview: ext question. 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 magnet to fall through the aluminum tube is much greater than is the time for the identical magnet to fall through the glass tube. Mass of magnet (kg) Tube length (m) Time for magnet to fall from position A to position B (s) Glass Tube 0.150 0.95 0.44 26 Aluminum Tube 0.150 0.95 0.76 Written Response—15%...
