Is this a mass change or disturbed local gravity?
I then dropped a string of 5 X neo disc magnets, 5mm dia x 3mm thick, down the same tube and it floated down taking 7 seconds to pop out the other side.
I tried the same experiment with an aluminium tube and observed the same results.
What is causing this phenomenon?
Could it be magnetic eddy currents in non ferrous material?
Has the mass of the neo mags been changed or is it a local gravitational disturbance?
