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

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

Magnetic tape is a medium for magnetic recording‚ made of a thin magnetizable coating on a long‚ narrow strip of plastic film. It was developed in Germany‚ based on magnetic wire recording. Devices that record and play back audio and video using magnetic tape are tape recorders and video tape recorders. A device that stores computer data on magnetic tape is a tape drivOver years‚ magnetic tape can suffer from deterioration called sticky-shed syndrome. Caused by absorption of moisture into the binder

has a rather low intensity magnetic field. Alnico magnet alloy is now mainly used in applications where the magnet will be exposed to elevated temperatures. • Rare Earth Magnets Samarium Cobalt (SmCo) and Neodymium Iron Boron (NdFeB) are called Rare Earth because Neodymium and Samarium are found in the rare earth elements on the periodic table. Both Samarium Cobalt and Neodymium magnet alloys are powdered metals which are compacted in the presence of a strong magnetic field and are then sintered

Production of magnetic flux A rotating magnetic field in the stator is the first part of operation. To produce a torque and thus rotate‚ the rotors must be carrying some current. In induction motors‚ this current comes from the rotor conductors. The revolving magnetic field produced in the stator cuts across the conductive bars of the rotor and induces an e.m.f. The rotor windings in an induction motor are either closed through an external resistance or directly shorted. Therefore‚ the e.m.f induced

Describe the major migrations into the Caribbean that greatly impacted society and culture. Migration is the movement of people from one place to another‚ but in this case‚ it is the movement of a group of people from another country coming into the Caribbean for better opportunities mainly‚ because of slavery. The major migrations into the Caribbean were mainly slavery‚ indentureship‚ encomienda and the plantation system. All these were the impacts of the historical processes. Influences of the
