Magnets, Smith ramp v 2

[sm0ky2]

it appears he is using a C & D notation for the magnetic polarities instead of N & S / + & - or what have you.

It won't matter much as long as they are same face up and opposing the car magnets.

But in actuallity one pole pushes harder (like poles),
and the other pole pulls equally harder (opposing poles or attraction of paramagnetic materials).
within the flux loop they are equal and opposite giving them a net force of = 0 .
but when you are using them to propell something like this and not use the attraction side of the loop then there is usually a "slight" diference by changing the polarity, that increases exponentially with flux density.

i.e. - if you are using neodyium instead of these iron-ferrite magnets, you may want to pay closer attention to which side "pushes" better.

G'day all,

Am I here missing something. It looks very much like the same phenomenon we have seen hundreds of times only with a different arrangement of the magnets.
