Self Induction And Related Phenomenon

Description
The topics discussed are electrical induction, super conductivity. A number of applications of induction is mentioned. How changing potential in heart cells kep heart pumping , electrocardiagram, defibllators and pacemakers are explained.Application of supercondutors to levitate is explained.An important use of this concept is Maglev trains.And finally the effect of levitation is demonstrated for a "woman" by running alternating current through a coil of wire above a conductor .
