The Principle of Induction states that if something x has happened in certain particular circumstances n times in the past, we are justified in believing that the same circumstances will produce x on the (n + 1)th occasion. Faraday’s law of induction, in physics, a quantitative relationship between a changing magnetic field and the electric field created by the change, developed on the basis of experimental observations made in 1831 by the English scientist Michael Faraday. P(1)=(1(1+1) 2) 2 = 1 This is true. Moreover, the principle of induction (and likewise its corollary the uniformity principle) applies equally to the material, mental and spiritual realms. The English physicist Michael Faraday, a brilliant experimentalist, was the first to demonstrate the converse effect: magnetic fields can be used to induce electric currents. Methods of inductive statistics (so called statistical induction) can under given assumptions to make general conclusions and to objectively enumerate their degree of confidence. The generation of Electromagnetic Induction can be achieved using two methods namely, Electrical Conductor is placed in a moving Magnetic Field; Electrical Conductor is steadily moving within a Static Magnetic Field ; Electromagnetic Induction Theory. This chapter deals with the latter principle. To “repel” away the incoming north pole) From the right hand grip rule, the current flow is as shown in the diagram. The energy transfer to the object to be heated occurs by means of electromagnetic induction. • Any electrically conductive material placed in a variable magnetic field is the site of induced electric currents, called eddy currents, which will eventually lead to joule heating.
