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

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

Lab #11 Faraday’s Law of induction Purpose: To prove Faraday’s Law of Induction using an oscillating wand which swings through a magnetic field. In addition‚ we studied the conversion of mechanical energy to electrical energy. Questions: 1. What are the possible errors in this experiment? There are a variety of sources of error which may have affected the results of this experiment. There could have been an error in the setup of the Rotary Motion setup or its setup within the Logger Pro program

CYLINDER SUS 304 STEEL TUBES USING MAGNETIC ABRASIVE FINISHING SETUP Abstract Magnetic Abrasive Finishing (MAF) is an advanced finishing method‚ which improves the quality of surfaces and performance of the products. Surface is finished by removing the material in the form of microchips by abrasive particles in the presence of magnetic field. The material is removed in such a way that surface finishing and deburring are performed simultaneously with the applied magnetic field in the finishing zone.

Magnetic particle inspection (MPI) - Is a non-destructive testing (NDT) process for detecting surface and slightly subsurface discontinuities in ferroelectric materials such as iron‚ nickel‚ cobalt‚ and some of their alloys. The process puts a magnetic field into the part. The piece can be magnetized by direct or indirect magnetization. Direct magnetization occurs when the electric current is passed through the test object and a magnetic field is formed in the material. Indirect magnetization occurs

generation the physical means such as gravity‚ vacuum or magnetic field is used for stabilization of the free flowing dry moulding materials. The development of unbounded casting process improves flexibility and enhances mould ability. The concept of unbounded casting is to change the kind of binder or to avoid substantial binder. Magnetic moulding is a type of unbounded moulding process in which a dry and free flowing magnetic steel shots or granules are used as mould materials
