The more current in the coil, the stronger the magnetic field will be, and the more energy the inductor will store. Because inductors store the kinetic energy of moving electrons in the form of a magnetic field, they behave quite differently than resistors (which simply dissipate energy in the form of heat) in a circuit. 7.2 Composite series magnetic circuit For a series magnetic circuit having n parts, the total reluctance S is given by: S = S 1 + S 2 +…..+ S n ( This similar to resistor connected in series in a electrical circuit ) Example 1 A closed magnetic circuit of cast steel contains a 6cm long path of cross-sectional area 1cm 2 and Abstract: Abstract—In this paper, we present a method to solve inverse problems of electromagnetic circuit design which are formulated as a topology optimization problem.

Inductance is a property of an electric circuit by which a changing magnetic field creates an electromotive force, or voltage, in that circuit or in a nearby circuit. Inductance is also defined as the property of an electric circuit that opposes any change in current. Magnetic Circuits The reluctance of a material to the setting up of magnetic flux lines in the material is determined by the following equation: Where is the reluctance, l is the length of the magnetic path, and A is the cross-sectional area. OHM’S LAW FOR MAGNETIC CIRCUITS For magnetic circuits, the effect desired is the flux . Current EM systems use magnetic components such as circulators, inductors, and isolators, but these are bulky and cannot be integrated with miniaturized electronic circuitry. This limits the utility of the magnetic components as well as their ability to impact overall system performance and function.

Inductance is a property of an electric circuit by which a changing magnetic field creates an electromotive force, or voltage, in that circuit or in a nearby circuit. Inductance is also defined as the property of an electric circuit that opposes any change in current. Ohm's Law does not exist for magnetic circuits, only for electric circuits. The analog of Ohm's Law in magnetic circuits is called Hopkinson's Law.

A magnetic circuit with its pertinent dimensions in millimeters is given in Fig- ure 2.18. The magnetization characteristic Of the magnetic material is shown in Figure 2.19. If the magnetic circuit has a uniform thickness Of 20 mm and the flux density in the air-gap is 1.0 T, find the current in the 500-turn coil. This e.m.f induced is called induced e.m.f and if the conductor circuit is closed, the current will also circulate through the circuit and this current is called induced current. Method to change magnetic field: 1. By moving a magnet toward or away from the coil 2. By moving the coil into or out of the magnetic field. Any movement of electrons constitutes an electric current, and any electric current produces a magnetic field. This even holds for permanent magnets. In this case, it is the movement of electrons in a particular orientation relative to their orbitals that leads to the permanent magnetic effect.
