Definition: The Series Magnetic Circuit is defined as the magnetic circuit having a number of parts of different dimensions and materials carrying the same magnetic field. Consider a circular coil or solenoid having different dimensions as shown in the figure below: Current I is passed through the solenoid having N number of turns wound on …
Definition: Mutual Inductance between the two coils is defined as the property of the coil due to which it opposes the change of current in the other coil, or you can say in the neighbouring coil. When the current in the neighbouring coil changes, the flux sets up in the coil and because of this, …
Definition: Self-inductance or in other words inductance of the coil is defined as the property of the coil due to which it opposes the change of current flowing through it. Inductance is attained by a coil due to the self-induced emf produced in the coil itself by changing the current flowing through it. If the …
Leakage flux is defined as the magnetic flux which does not follow the particularly intended path in a magnetic circuit. Taking an example of solenoid you can explain the leakage flux and the fringing both. When a current is passed through a solenoid, magnetic flux is produced by it. Most of the flux is set …
Definition: The emf induced in a coil due to the change of flux produced by another neighbouring coil linking to it, is called Mutually Induced emf. Let us take an example to understand the phenomenon of mutually induced emf. Consider a coil AB. Coil B is having N2 number of turns and is placed near another coil …
Definition: Self-induced emf is the e.m.f induced in the coil due to the change of flux produced by linking it with its own turns. This phenomenon of self-induced emf can be further understood by the following example given below: Consider a coil having N number of turns as shown in the above figure. When the …
Definition: The number of magnetic lines of forces set up in a magnetic circuit is called Magnetic Flux. It is analogous to electric current, I in an electric circuit. Its SI unit is Weber (Wb) and its CGS unit is Maxwell. It is denoted by φm. The magnetic flux measures through flux meter. The fluxmeter …
If Electric current is passed through a simple magnet wound with a coil of insulated wire and the magnetic field is produced the magnet formed by this process is called Electromagnet. The core of the magnet which is wound with the wire is made of ferromagnetic or ferromagnetic materials such as iron. The magnetic field …
The name Faraday’s Law of Electromagnetic Induction is given in the name of a famous scientist Michael Faraday in the 1930’s. It gives the relationship between electric voltage and changing magnetic field. Faraday’s Law of Electromagnetic Induction states that “ the magnitude of voltage is directly proportional to the rate of change of flux.” that …
The Difference Between the Magnetic and Electric Circuit are explained considering various factors like the basic definition, relation between Flux and Current, Reluctance and Resistance, EMF and MMF, different analogies of both the circuits. Like its density and intensity, laws applicable in the circuit, Magnetic and Electric lines, etc. The Difference Between Both the circuits …
