Re: [EVGRAY] Triple thick BiTT

Hi Warren, Garry,

The work done to remove the magnetic poles apart from each other should in theory be the same (energy preservation). If some parametric change happens this may not actually be the case. When sliding the magnetic poles apart the distance is longer but with a weaker force. When pulling the poles apart the force is greater but the distance is less than when sliding the poles apart. The work done is the force integrated over the distance moved. In theory this work is the same in a conservative force field. Howard Jonson managed to make his self-runner but at the cost of demagnetizing the magnets. When pulling apart the magnets the magnetic field falls of very fast with distance (something between the square to the cube of the distance). When sliding apart the magnets the field falls of in a more linear to square way. A finite element magnetic field solving program could perhaps calculate the energy.

A lever or a pulley or a gear is another way of pulling away something with a lot less force even though the work done is the same. The distance is increased as the force is decreased.

Motors and generators have the rotor slide along the field of the stator. There are some experimenters using pistons moving into and out of the magnetic field to change the air gap length and thus the reluctance of the magnetic circuit.

Regards
Ole

 Gerry Help me with a magnetic issue, a little sideways from the topic, two magnets attached NS can not be pulled apart very easily except with extreme force, yet pulled 90 degrees to the line of attraction, other than obvious friction, get easier quite rapidly, leaving that zone of attraction.
 This quirk, is the trick the Kromery exploits, I believe, along with mechanical inertia.
 I am not sure how this phenomena is put mathematically, or who's rule it fall under.
