Consider the gravity yet?

I know potential energy -velocty-kinetic energy -mass- attraction magnetic- gravity- all these parameters can be calculate ! Thanks !

tu devrai essayer d'en faire un circulaire

Voir Sticky spot 2

The sticky spot is due to magnetic induction between the spherical magnet and the aluminum track. If the track was made of copper, the sticky spot will also occur. If the track was made of plastic, there will not be a sticky spot.

For the plastic ! exact! it's better but there is a sticky spot again !!!

Damn ! I want the nice PC in the background at 2'40'' !!

Keep having magnetic fun !

nice video ^^

very good

if you cut a hula hoop down its circumference you can make two nice round tracks for the ball in.

I just got it. The spherical ball is not a magnetic sphere. The magnets below are still interacting with the steel spherical ball after it gets over the hump. That is why the plastic ramp still has the sticky spot.

[ftmiller12]

However, you have me baffled on why there is a sticky spot with the plastic?

[ftmiller12]

You are correct, the sticky spot is due to eddy currents in the conductor materials (aluminum, copper); however the eddy currents are created by the applied (induced) magnetic field from the magnet, which causes an electrical current to swirl. This swirling electrical current in the conductor causes an induced magnetic field that in the conductor which is opposite in direction and slows the spherical magnet (sticky spot). All in all, we are speaking the same language regarding the sticky spot.
