High reluctance
WebJan 21, 2024 · In physics, reluctance is the measure of a material’s resistance to magnetic flux. A material with a high reluctance is said to be a good insulator, because it impedes the flow of magnetic flux. Magnetic resistance in an electrical circuit, also known as the formal analog of resistance, can be distinguished from a magnetic circuit resistance. WebTo avoid high reluctance at joints, laminations are stacked by alternating the sides of joint. That is, if joints of first sheet assembly are at front face, the joints of following assemble are kept at back face. Types of transformers …

WebFeb 1, 2008 · Call reluctance is an emotional short circuit that diverts energy from the act of prospecting to the act of procrastinating. Instead of making calls, call-reluctant salespeople are busy preparing to prepare and avoiding the phone. They allow their fears to stand in the way of their goals – and it extracts a high emotional and financial cost. Magnetic reluctance, or magnetic resistance, is a concept used in the analysis of magnetic circuits. It is defined as the ratio of magnetomotive force (mmf) to magnetic flux. It represents the opposition to magnetic flux, and depends on the geometry and composition of an object. Magnetic reluctance in a … See more The term reluctance was coined in May 1888 by Oliver Heaviside. The notion of "magnetic resistance" was first mentioned by James Joule in 1840. The idea for a magnetic flux law, similar to Ohm's law for closed See more In both AC and DC fields, the reluctance is the ratio of the magnetomotive force (MMF) in a magnetic circuit to the magnetic flux in this circuit. In a pulsating DC or AC field, the reluctance … See more • Constant air gaps can be created in the core of certain transformers to reduce the effects of saturation. This increases the reluctance of the magnetic circuit, and enables it to store more energy before core saturation. This effect is also used in the flyback transformer See more
