Magnetic Susceptability Michael J. Horan II Abstract: The change in weight induced by a magnetic field for three solutions of complexes was recorded. The change in weight of a calibrating solution of 29.97% (W/W) of NiCl2 was recorded to calculate the apparatus constant as 5.7538. cv and cm for each solution was determined in order to calculate the number of unpaired electrons for each paramagnetic complex. Fe(NH4)2(SO4)26(H20) had 4 unpaired electrons‚ KMnO4 had zero unpaired electrons‚ and

a) Derive an expression for the magnetic field B at a point of distance r‚ from an infinitely long wire that carries a current I. Your derivation should include the direction of the magnetic field with respect to the direction of current flow. Verify your expression by using the experimental results obtained. If your results do not show the expected relationship‚ explain why. In order to derive an expression for the magnetic field B at a point of distance r‚ from an infinitely long wire that carries

HISTROY The evolution of active magnetic bearings may be traced through the patent issued in this field. Earlier patents for magnetic suspensions can be found but are excluded here because they consist of assemblies of permanent magnets of problematic stability per Earns haw’s Theorem. Early active magnetic bearing patents were assigned to Jesse beams at the university of Virginia during World War II and are concerned with ultracentrifuges for purification of the isotopes of various elements for

The magnetic interaction is described in terms of a vector field‚ where each point in space (and time) is associated with a vector that determines what force a moving charge would experience at that point (see Lorentz force). Since a vector field is quite difficult to visualize at first‚ in elementary physics one may instead visualize this field with field lines. The magnetic flux through some surface‚ in this simplified picture‚ is proportional to the number of field lines passing through that surface

The Magnet Compass Research Paper Many people believe that the magnetic compass is one of the most important inventions ever created‚ next to penicillin and the panini maker. It turns out that there is an entire story that lies behind this marvelous invention’s history and how it works. When most people think about a compass‚ they think of “that thing that shows which way is north”. But the truth is that it’s much‚ much more than that. This is an example of how much we take the things we have
