From the positive posts from you, it appears that you are a very smart person. Why do you lower yourself by insulting people? Yes I know that negativity get to you sometime but I think you’re a better person then that.

@ Low Q
Yes everyone has been taught that magnets have potential energy, just like a weight lifted to a height. But what said weight (maybe a cement brick) can’t do is hold it self up to that height like a magnet can. What is the force that holds a magnet to the bottom of a metal beam? Why is it that a cobalt magnet is not radioactive when cobalt is? Where did the radiation go? Is it being used by the structure of the molecules to product the magnetism? Too many questions about magnets to just say “It a conservative force, end of discussion” I would hope that this forum is about developing ideas, not to tell people that they are wrong. We don’t need your enlightenment. It’s just like watching TV if you don’t like what is on the channel you are watching then you change the channel. Or do you never change the channel. Then write to the TV station and tell them that they are not broadcasting the right show. Sorry, I don’t know everything about magnets and either do you. Wisdom is knowing that you don't know.

There is many questions about magnets for those who don't know much about them. What most of us know is that they can attract or repell other objects. This is what we call magnetic force.
This force is determind by the magnetic flux, and how much another object is affected by magnetism. If we know this, the basic thing we talk about is forces, and how the force is affected by a materials properties. So then we know that a magnet is supplying forces which is determind by its magnetic properties, and the objects around it.

So what is so mysterious with a levitating mass due to magnetism? The brick isnt magnetic, and if it was, it could levitate in one condition: The magnetic direction must be aligned to counterforce gravity. So what happen with the magnetic brick if aligned the opposite? You will make the brick twice as heavy than its mass should promise. In sum there is no change in mass and the weight. So no change in mass, potential energy, or work is carried out.

We also know that the magnetic force is constant if the magnet remain its magnetic properties permanently (cobalt or not), and all other objects around it remain the same properties. If this is fulfiled, there will never be any change in the properties and the magnetism. No change means no energy.

All magnetic forces in a system will act and counteract equally as long there isnt any change in the properties within the system. These properties can however be changed by sypplying energy externally into the system. If we don't do that, nothing will ever happen. - We can sit there and wait till the brick do work while it remains in the same position.

OK Low Q
What molecular, atomic, quantum or any other mechanism holds the radiation in, in a cobalt magnet?
Or is it consumed to create the magnetic field?
Can you alter the effect by external force?
Do you know what makes a magnet a magnet?
Do you know the precise mechanism that products the magnetic fields or are you just repeating what you learned in school?
Please enlighten with your vast knowledge in this area.

I saw the video that you did with the balance affect with the 25 pound pipe. I stopped there and did not watch any other because your theory that the two magnets are stronger together than apart is wrong. I am sorry to say but the reason that they seem stronger is because the magnetic poles for the rectangle magnets are in the center. The farther away from the pole the weaker the attraction.

Ergo, Period, is a very big word

In this case it is justified.

Time will be telling forever when it comes to tri-gates.

Just have another look at the poor motion in the video.
There is no torque what-so-ever to speak of. It's barely passing the gates.
Slightest shaft load from a connected generator will stop it.
Hell yeah....even the lite drag from a unloaded generator will immediately stop it.
