2. Magnetic Field Electric field 1) A distribution of electric charge at rest creates an electric field E in the surrounding space. 2) The electric field exerts a force F E q E on any other charges in presence of that field. Magnetic field 1) A moving charge or current creates a magnetic field in the surrounding space (in addition to E). The magnetic flux is the amount of magnetic field lines cutting through a surface area A defined by the unit area vector If the angle between the unit area and magnetic field vector are parallel or antiparallel, as shown in the diagram, the magnetic flux is the highest possible value given the

the current loop would create the magnetic eld shown by the pattern of the iron lings. This magnetic eld is the same as the eld that would be produced by a permanent magnet. We can quantify the strength of that hypothetical magnet in terms of a mag-netic moment m (Figure 1.2b). The magnetic moment is created by a current i and also Jun 08, 2016 The purpose of our study was the evaluation of toxicological effects of silica-coated gold nanoparticles (GNPs) and static magnetic fields (SMFs 128 mT) exposure in rat lungs. Animals received a single injection of GNPs (1,100 g/kg, 100 nm, intraperitoneally) and were exposed to SMFs, over 14 days (1 h/day).

Apr 17, 2018 Three types of metals interact with magnetic fields ferromagnetic, paramagnetic and diamagnetic metals. Ferromagnetic metals are strongly attracted to magnets the rest are not. Magnets also attract paramagnetic metals, but very weakly. Diamagnetic metals repel the magnet, though the force is typically very weak. Examples of diamagnetic substances are copper, gold, antimony, bismuth, silver, lead, silicon, mercury, etc. The electrons orbital motion gives rise to an orbital magnetic moment. In addition to this, the electrons tend to spin around their own axis, creating a spin magnetic moment. ... Magnetic field direction is the same as that of the ...

In its pure form, gold is non-magnetic and shows only a weak repulsion towards magnets like all diamagnetic metals. Gold is both paramagnetic and diamagnetic. Both of these effects are weak compared to ferromagnetism, but present. A strong enough permanent magnet will attract gold if moved slowly, and a rapidly varying magnetic field will repel it. The tunable semiconducting response of DNA in the presence of external electromagnetic and thermal fields is a gift for molecular electronics. The impact of temperatures (25-55 C) and magnetic fields (0-1200 mT) on the current-voltage (I-V) features of Au-DNA-Au (GDG) structures with an optimum gap of 10 m is reported.

Jan 21, 2014 Magnetic gradiometry is also an important near-surface exploration method in the investigation of gold and silver deposits. The first vertical derivative of the residual total magnetic field provides value-added products that may contribute to the geological interpretation of magnetic data.
