When the magnet box falls in the glass tube, although the magnetic flux passing through the glass tube changes, the glass tube is an insulator and does not generate induced current, so that the electromagnetic damping phenomenon does not occur in the glass tube, and the magnet box does free-falling body movement.
②, facilitating students to understand the phenomenon of electromagnetic damping and deeply analyze the conditions generated by the electromagnetic damping.
Analysis of experiments 3, 4 and 4-1 revealed that the induced current generated on the aluminum tube does not necessarily have to be directed around the aluminum tube, but may be directed in other directions.
③, the student can understand the damping movement and the non-damping movement, and master the movement rule of the magnet in the metal tube.
