Newton's Magnets

<< < (2/21) > >>

Floor:
Please note that...

The inner magnet's instalation and / or removal is without doing work against magnetic forces.
This is due to a balance between the attracting and repelling  forces along the vector (line) of its travel.

Low-Q:
I looked through your PDF. The concept looks interesting.
Have you simulated this inn FEMM?


Would the attached design, that is based on the similar concept work in a similar way?
I often make other designs of the same concept to see if I do mistakes that I might miss on the first design.
The design in my poor drawing is easy to simulate in FEMM too. Just measuring torques at different positions of the wheels.


A vertical stationary magnet should do the same/similar job as the centermagnet in your PDF.


Since this vertical magnet isn't a piece of iron, it has its own magnetic field that does not prevent the rotormagnets to pass (?). A simulation will show how it works


Vidar.

Low-Q:
I figured it out. In your design, the lower magnet and stationary magnet adds up a stronger magnetic field. They are attracted to eachother, but since they add up, the repulsion between these two and the top magnet is stronger than the attraction bewteen the other two.
That means it will be a sideways force on the stator magnet when you try slide it out. In fact, the force is going in the right direction, but the total force between the two moving magnets is also repulsion, not neutral.

I simulated a rotary version of this. It ends up in zero torque.

I did some rotary builds and found little or no usable torque.  I have femm but never use it.
My designs come from real world experiments

I never got stuck on the idea that a free energy device must have a spinny thingy
 and / or a flashing thingy.  Most of these designs don't.

Inefficient devices need to spin, so they conserve momentum, OU devices don't.

Watch the short video below to a real demo of the Newton's magnets principles.

There are many directions in which the magnets prefer to act.  Limiting their motions
to specific directions (with track systems) is why the designs work.

I've watched the video. I'm not sure if you can feel any counterforce when using ferrites, with a relatively large spacing, in combination with a large heavy structure with friction.
Magnets are tricky. They tend to not do what they are told :-)
What we do know for sure, is that the fields from one magnet to the other have a magnetic force only when the field is not perpendicular to each other. As soon as on magnet is moving, the field starts to line up with other fields, and then repel or attract.


Looking at AC-transformers, will explain this well. The transformation will not take place if the primary coil is placed perpendicular to the secondary coil. The rule of thumb when designing crossover networks for speakers, the inductors are never placed in such way that they can transfer energy from one inductor to the other. If they do, signals from one frequency range will be transferred to a speaker driver that is not supposed to play that same frequency range.
