Electromagnetic Induction is the governing principle that is used to explain how electric generators (also called alternators), microphones, electric guitars, and transformers operate. It is a valid method of dealing with data, independently of the sort of data involved, i.e. Describe an experiment to demonstrate electromagnetic induction. Current produced by the relative motion of coil or magnet is called induced current, set up by an induced electromotive force or EMF. From this, we can conclude that emf is induced whenever the magnetic field lines are “cut” by the coil. Mathematical Induction Class 11 Notes - Principle of Mathematical Induction. A self-inductance or mutual inductance is varied to measure required physical quantities like displacement (rotary or linear), force, pressure, velocity, torque, acceleration, etc. This produces a Voltage or EMF (Electromotive Force) across the electrical conductor. The formation conductivity distribution in the borehole vicinity is critical information required in formation evaluation and geosteering applications. The energy transfer to the object to be heated occurs by means of electromagnetic induction. It is interesting to note that Faraday had little formal schooling, so mathematics was by no means his strength. 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. The Internet Encyclopedia of Philosophy puts it this way: This chapter deals with the latter principle.
