So, today, before starting our discussion regarding the fundamentals of machining. Electromagnetic theory online course video lectures by iit. So these are the questions that cannot be answered from the. Among these techniques, electromagnetic forming is a highspeed process, using a pulsed magnetic field to form the work piece, made of metals such as copper and aluminum alloys with high electrical conductivity, which results in.
It is an impulse or highvelocity forming method using pulsed magnetic field by application of lorentz forces to the work piece preferably made of highly electrically conductive material without having working medium and mechanical contact. This course introduces students to handling electromagnetic theory using vector calculus. Electrohydraulic forming and electromagnetic forming topics covered 1 introduction 2 process principle 3 constructional details 4 advantages and disadvanta slideshare uses cookies to improve functionality and performance, and to provide you with relevant advertising. Nptel provides elearning through online web and video courses various streams. Major topics include electromagnetic waves, transmission lines, waveguides, and antenna fundamentals.

Iii electromagnetic forming the electrical energy stored in a capacitor bank is used to produce opposing magnetic fields around a tubular work piece, surrounded by current carrying coils. The description of nature is essentially probabilistic, with the probability of an.
Sharma, department of mechanical engineering, iit roorkee. A system is completely described by a wave function. Electromagnetic theory video course course outline electromagnetic theory is a core course in electrical engineering curriculum. It is an impulse or highvelocity forming method using pulsed magnetic field by application of lorentz forces to the work piece. The characteristics of this process are similar to those of explosive forming. This is very much associated with all the conventional forming, most of the conventional forming processes applied to sheet metal forming. The goal of electromagnetic em shielding is to protect electrical and electronic components and assemblies from external em fields or to prevent that em fields produced by apparatus and systems. Then the problem is the time required will also be high, then and another problem is the spring back problem. Electromagnetic forming emf is a noncontact forming technique.
