Paramagnetic & Diamagnetic Field Experiments


SKU: RH-ESTC2016-FE Categories: , ,


The magnetic field that we learn about in the physics texts books we call the paramagnetic field, (a flux field). In the non-academic world, there is some discussion of another aspect of the magnetic field, called the diamagnetic field. The diamagnetic field, where it occurs, is always perpendicular to the paramagnetic field and is thought to be biologically active.

In this talk, we describe experiments by which the diamagnetic field by the Bloch region and by the poles of a magnet may be measured using 3-axis Hall effect milligaussmeters, magneto-resistive milligaussmeters and sensitive differential electrometers. Our experiments provide evidence for the existence of a diamagnetic field and the vortex of the paramagnetic field.

It is well known that a changing paramagnetic field will induce a voltage across a coil that is positioned in the changing paramagnetic field. The polarity of the induced voltage is such that if the coil is connected to a load, the paramagnetic field in the coil, produced by the current in the coil opposes the primary changing paramagnetic field that produced it. We designed experiments using a rotating circumferentially polarized ceramic ring magnet to determine whether a moving diamagnetic field can induce a diamagnetic field and if the induced current of a coil affected by the primary diamagnetic field is entropic or counter-entropic.
