Metal recovery from industrial waste has recently been shown [101] to be an active area of magnetic field applications, the base system ranging from mine-waste to cable scrap. Fe, Co, Nl, Cr, Mn, Mo, Tl, Va, W, Ta, U, rare-earth metals and precious metals are the most obvious candidates for recovery in magnetic fields, although other substances, e.g. Zn, Pb, Mg, Ca, have also been the subject of successful recovery studies [e.g. 71].

A suitable pulse sequence can then set up a state in which the net magnetisation of the crystalline phase is zero and that of the non-crystal-line phase is in equilibrium with the applied magnetic field Application of a 90° pulse after a time t and analysis of the subsequent FID then allows the determination of the magnetisation M t) of the crystalline phase as a function of time as it relaxes back towards equilibrium by the transference of magnetisation to it by spin diffusion from the non-crystalline phase. 

The applications of superconducting materials can be summarized in two main categories high-magnetic-field and low-magnetic-field applications. 

Low-magnetic-field applications. These applications include Josephson-effect devices, magnetic-flux shields, transmission fines, and resonant cavities, all of which require superconducting materials having a high critical temperature and a high critical magnetic field.

Magnetic field application can also induce a strain in a gel when a structure or species sensitive to the magnetic field is contained in it. We first proposed the idea of applying a super paramagnetic fluid to a gel. The gel was found... 

In the present section we wish to show that the principle of minimum entropy production is applicable also to the stationary state in a magnetic resonance experiment, in which a collection of spin magnetic moments are subject to a circularly polarized magnetic field perpendicular to a constant magnetic field. Application to this type of phenomenon is done by a reinterpretation and modification of Klein and Meijer s method. This has been done by Klein and he has shown that Overhauser processes of producing nuclear polarization satisfy the principle of minimum...
