Quantum field of magnet
The quantum field image of magnets shown, includes also visual information about their domain wall or else Bloch wall which is considered as a quantum effect therefore the name "Quantum field of magnet" is given when it is observed via the ferrolens. Other alternative magnetic field visualization methods using ferromagnetism are not showing this kind of information.
Relative hard ferromagnetic materials and macroscopic sensors with a large magnetic anisotropy K and very low magnetic reluctance like iron when used in magnetic field mapping applications show the highest magnetic potential imprint of the field of a magnet.
However, there is a second existing at the quantum level, lowest, ground state (i.e. domain wall) magnetic potential field pattern around every magnet where magnetic flux circulates on two distinct and separate hemispheres as shown by the ferrolens. Each magnetic hemisphere is residing on each pole of the magnet. The two hemispheres are placed back to back and joined tangent to the domain wall of the magnet, resembling the Greek letter theta θ. Gyromagnetic ratio γ of magnet is preserved in this new field geometry observed since it consists essentially of two joined hemispheres making up a sphere.
Soft magnetic materials and quantum, nanosized sensors with lower magnetic anisotropy in a superparamagnetic configuration like a magnetite Fe3O4 diluted in an hydrocarbon based or water based carrier solution, thin film of ferrofluid, are able to show as demonstrated, in real-time the quantum field image of a magnet. In general the Quantum Field of Magnets (QFM) is attributed to the Quantum Decoherence phenomenon.
