Several Suggested Experiments
1. Two small bar magnets are precisely aligned so that the north pole of one faces the north pole of the other, and the two magnets are separated by a distance great enough so that the "fields" no longer interact to any currently measurable degree... say 10 feet. The alignment would be vertical; one magnet 10 feet above the other. The upper magnet is then heated until it reaches the Curie Point. As that temperature is reached, what we'd be looking for is an extraordinarily brief "push" on the lower, unheated magnet. If that unheated magnet is on a sensitive scale at the time the "push" occurs, for example, the impulse might cause its measured weight to increase momentarily.
Alternatively, a first-surface mirror could be attached to the south end of the unheated magnet, with a laser reflecting off the mirror. At the instant in which the heated magnet reaches the Curie Point, the "push" we're looking for might be evident in a small change in the beam's angle of reflection. Of course, with such an approach, the vertical alignment described above would no longer be necessary, as long as the two magnets remain precisely aligned.
If this effect is NOT observed, it doesn't necessarily invalidate the theory; it's possible that the effect happens so quickly, or is so tiny, that it eludes our ability to detect it. In that case, the experiment should be tried again, this time with a more powerful heated magnet and thus, a more powerful pulse. Alternatively, the heated magnet could be encased in a constantly charged DC coil, with the temperature of the magnet rapidly raised and lowered to just above and just below the Curie Point. This should generate a series of pulses, hopefully making detection easier.
2. A second experimental configuration would use only one bar magnet, which is heated while precisely aligned so that its north pole is aimed at the edge of an empty cylindrical coil standing 10 feet away. A sensitive oscilloscope would be attached to the coil. At the moment the magnet reaches the Curie Point, look for a very brief electrical current to be generated in the coil: the result of an interaction with the passing "pseudomonopolar" pulse.
3. A third approach would replace the coil in the above configuration with a large number of micromagnetic particles (the smaller the better) suspended in a low-viscosity gel. The container holding particles and gel would be placed so that any pulse emerging from the heated magnet would pass through the gel. What we'd be looking for is a sudden, brief alignment of the magnetic microparticles as the sought-after pusle passes through.
In all cases, what we're looking for is a qualitative, rather than a quantitative, result. In other words, it will be enough at this stage to simply detect the existence of a pulse which cannot be explained by current theory. Only if such a pulse is indeed detected will it become worthwhile to address such questions as: How powerful is the pulse? How long does it last? How quickly is it travelling?
