The magnet is not attached to the refrigerator. Thus it is resisting gravity every moment. And that is work. Of course, modern science gets around this buy saying there is no movement. But, that is just in one frame of reference.
And then, out comes magnet motors. Things that spin by the power of magnetic force of permanent magnets.
Resisting gravity without moving isn't wrok. Work needs force and displacement, and a static magnet has zero of that over time in any frame you pick. If something spins, where's the energy coming from, because it's not from < permanent magnet magic. Magnets don't do continuous power by themselves and every claimed magnet motor either sneaks in input or stalls once losses catch up, teh basic thermodynamics still holds.
Yep, that is what Modern Materialistic Science says, but it isn't true. There are magnet motors now, they just don't have enough torque to produce useful work. But, that will be solved soon.
Hope is cool, but a static magnetic field doing no work at zero motion still holds. If a magnet motor can't beat friction and losses, there's no net work. Do you have measured toruqe and and rpm against any inputs? Show a continuous output above all inputs, I'll be the first to admit I'm wrong.
On work, is a table doing work holding stuff up off the floor? According to one view, no. According to another view, yes. The weight on the table is causing strain throughout the structure, but it is also not moving so it is not causing heat buildup (that we can feel), however, at any moment, you may find the table bursts into pieces and the stuff is now on the floor.
On magnets, the field is not static. Tesla said that his discovery of the rotating magnetic field is his most important ever.
Our problem is that we like to make things balanced, so much so that we don't really have good ideas of imbalance, or a continuous imbalance. This is the secret to magnet motors and later, free-energy devices. Today, the magnet motors are perpetual motion machines, little anomalies. They continue to spin years later.
If i create a magnet motor, i will only tell people about it after i get useful work out of it, and then i will tell EVERYONE how to build it as fast as possible.
