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

Nickel content. Alnico magnet alloy has high maximum operating temperature and a very good corrosion resistance. Some grades of Alnico alloy can operate upwards of 1000C. Magnets made with this alloy are available in a variety of grades and dimensions and they are usually cast. Alnico magnet material is an older technology and it 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

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

Jennifer Smith G.G. Toys: Case study #2 G.G. Toys was a toy manufacturer facing problems with productivity and profitability. The company found a profitable product in their Geoffrey doll and Specialty branded doll #106. Retailers could customize to the specifications and buying habits of their customer base. On average‚ the Geoffrey Doll cost $19.19 to produce‚ and the #106 doll $23.74. To access in a study of their overhead cost for both of their plants‚ research showed that: 1. A setup

essay about your play development. “The inherent purpose of any toy has always been to entertain or occupy a child. But toys are also frequently used in other ways‚ such as educating children or teaching them about important rituals. No matter their purpose‚ toys are an important influence on the emotional‚ mental‚ and physical development of children.”(Microsoft Encarta 2009) Toys may vary from dolls‚ cars‚ puzzles‚ construction toys‚ board games and play sets down to simple materials such as clay
