A mono pole magnetic structure? [Comments Locked] | 37 comments (37 topical, 0 editorial)

Thanks for your reply. The experiment is more theoretical than practical and is one of many experiments based on by belief that if you understand magnetic flux (in isolation), you will soon understand everything.

It is based on the idea that if you cannot meet the 'master', then knowing his servants will tell much about him.

Magnetic flux is unique in that it is not corrupted by the act of perception as it operates outside time and lacks mass. It is a pure reference or datum plane.

If such a structure was possible it could unlock the secrets of gravity and also allow magnetic circuits that used induction (Eddy Currents) to increase not reduce output.

Hope this helps you understand why the construct interests me.

Best wishes,

aimulti

Sorry, but the magnetic field also obeys the dictates of the Special Theory of Relativity.  You think this thing could be built.  Perhaps it can't.  Perhaps it would take infinite energy to do so.  You can calculate the energy contained in a shell of charge by bringing infinitesimal amounts of charge onto the shell and summing (integrating) all the amounts of work or energy needed to do so.  Can you do a similar calculation for your monopolar magnetic sphere?

From a practical standpoint when you try to bring the last few magnets onto the sphere they will insist on flipping.  If you try to use some sort of machine to hold the magnets, the magnets will likely disintegrate as the individual magnetic domains flip causing strong stresses in the magnets.  Just because you can conceive of something doesn't mean it can be built.

The mechanical problems of assembling the sphere have been worked out. It requires a fairly complex jig with hydraulic actuators and retracting sleeves. When you say the magnets will 'flip', do you mean physically or magnetically?

The mechanical flip can be stopped, as I said. The internal magnetic 'flip' or demagnetizing is a function of the B and H curve of the material. For 55MGOe NdFeB the ratio is about 7:1 so if the imbalance exceeded this ratio the magnet would fail.

In the proposed design the magnetizing force and demagnetizing force is kept in limit by the pinned flux.

The greater the contamination of the super conducting material, the greater the pinning and 'draining' of one side of the circuit.

The device does not require the addition of energy for containment, like a Stellarator or Tokamak, as it is a relative field block not an external field bottle.
