At 4:27 you are talking about the rate of field intensity drop off. Biot-Savart Law says the drop for electro-magnets is an inverse square of the distance. The same is true of gravity. So I would be interested in seeing a demonstration of what you are saying regarding ferrite extending farther and dropping off slowly because I think you might mean something else, which I do not understand. I think neodynium extend farther, especially if you measure from the centre.
