This paper presents an experimental study on the behavior of swelling soils saturated with magnetized water. Parameters investigated were free swelling and swelling pressure of clayey soil saturated in magnetized water with four magnetic intensities (500, 1000, 1500, and 2000). Three specimens (extracted from three different locations in Iraq) were tested in different magnetic intensities and compared with a soil specimen saturated with ordinary water. Magnetized water was produced by passing water through a P.V.C. pipe bounded with a magnetic field. It was found that the value of swelling pressure and free swelling (of the soils saturated with magnetized water) increase with the increase of magnetic intensities. In specific, the value of free swelling and swelling pressure ranging between 26.38% - 59.0 % and 32.16% - 161.16%, respectively.

Loss Of Weight

This paper concerns the inductive experimental study of corrosion products of the medium carbon steel CK45DIN using magnetized water as hardening media, where the water has been exposed to a magnetic field of 1000 Gauss and 2000 Gauss, respectively, for time durations of 1 to 5 hours, with a volumetric flow rate of 4 gal/min. Medium carbon steel CK45DIN samples were exposed to air as corrosive environment for reasonable time interval, and the corrosion product was weighed in order to determine the loss of weight. The results showed that the corrosion rate of all samples decreased as the experiment progresses over time. Corrosion resistance of the medium carbon steel CK45DIN increased when we raised its temperature to 870°C for 40 minutes and hardened by magnetized water applied in a magnetic field with a strength of 1000 Gauss for 3 hours as compared with the sample hardened by normal water.

Fluid Behaviour

This paper presents the results of an experimental study of the influence of an external magnetic field on the shear flow behaviour of a magnetic fluid based on barium hexaferrite nanoplates. With the use of rheometry, the magnetoviscosity and field-dependent yield-stress in the fluid are evaluated. The observed fluid behaviour is compared to that of ferrofluids with magnetic nanoparticles having high dipole interaction. The results obtained supplement the so-far poorly studied topic of the influence of magnetic nanoparticles’ shape on magnetoviscous effects. It is concluded that the parameter determining the observed magnetoviscous effects in the fluid under study is the ratio V2/l3, where V is the volume of the nanoparticle and l is the size of the nanoparticle in the direction corresponding to its orientation in the externally applied magnetic field.

An experimental study is carried out on the effects of nuclear mass on leading particle multiplicity and multiparticle production with the help of an emulsion stack exposed to 50 GeV/c π− beam under a strong pulsed magnetic field. The study of the effect of nuclear mass on the forward–backward asymmetry in a π−–A collision is also carried out using the grey particle multiplicity data. The results support the concept of "formation length" of radiation. An attempt is made to explain the space–time structure of hadronic matter in terms of the additive quark model of multiparticle production.

Magnetic Well

Detailed measurements of the trapped magnetic fields and currents in plasma structures generated by conical theta-pinches are reported. Studies of these structures interacting with a magnetic barrier, and with each other in a collision at the centre of a magnetic mirror, are reported. The magnetic well formed by the collision has been studied by simultaneous use of several diagnostic techniques. The measurements are in agreement with a force-free, collinear magnetic field configuration (Wells 1972). Arguments relating superposability and collinearity of flow fields to these observations are given.

A plasma produced by a helical RF structure of the Lisitano type is investigated. Measurements of electron density, electron temperature, and plasma stability are reported as a function of RF frequency and power, magnetic field strength and geometry, and neutral argon pressure. It is concluded that at moderate power (~20 W), electron cyclotron resonance is important in the power absorption process.
