Perpetuum mobile 5
This is really a simple demonstration, why all magnet or gravity related perpetuum mobile machines won't work.
As it can be seen from rhe picture, we simply put a megnet under a cylinder.made of iron. The magnet is not pozitioned under the rotation center, so it atracts one side of the cylinder more than the other. That is why the cylinder startes to rotate.
Unfortunately, this thinking is wrong. All parts of the cylinder that fall in the greater gravity (magnetic) level must be pushet out, as well. All the work, that a part of cylinder gets when it's mooving toward the greater gravity (magnetic) level is needed when it is pushed back out of it..
That is the reason vhy all gravity and magnet bazed perpetuum mobile machines cwill never work.
