In this video, self inductance and mutual inductance are. The influence of frequency upon the selfinductance of coils. Let us discuss, what is electromagnetic induction and its effect. We define inductance l as magnetic flux current here n is the number of coil turns in multiple coil systems there is magnetic coupling between the coils hence mutual inductance m here l. As the current increases, the magnetic flux through the loop due to this current also increases.
For this purpose, we have proposed a practical method called multiport transformer model to reduce the computation time in calculating these parameters. Self inductance free download as powerpoint presentation. This mutual inductance is true irrespective of the size, number of turns, relative position or orientation of the two coils. Chapter 6 inductance, capacitance, and mutual inductance. The coefficient of self inductance is also defined as the e. In this video, self inductance and mutual inductance are explained conceptually in a very simple way and then. Like capacitance, inductance has to do with the geometry of a magnetic device and the magnetic properties of the materials making up the magnetic device. Introduces self inductance with examples of a solenoid and a toroid. Mutual inductance formula two coils have a mutual inductance of 1h when an emf of 1v is induced in one coil by current changing at the rate of 1 as in the other coil. Experimental and simulation study on inductance and.
