one: English: Magnetic Circuit
Two: the definition of 1: magnetic circuit: closed loop generates a certain strength in which the magnetic field with strong magnetic material. 2: is mainly composed of a magnetic material composition, forming a closed magnetic flux channel medium combination in a given region. Iron core coil, 3: general by the through current to the excitation field consists of a soft magnetic material, and the appropriate size of the air gap form
Three: magnetic circuit magnetic circuit is defined by one or a plurality of permanent magnets, the current carrying wire, iron according to a certain shape and size composition, component is formed by the specific work of air gap magnetic field. The soft can be pure iron, low carbon steel, Ni-Fe alloy, Ni-Co alloy material with high permeability. Iron is also called the yoke, it plays the control flux flow, increasing the local magnetic induction intensity, prevent or reduce the magnetic leakage, and improve the mechanical strength of the whole member role in the magnetic circuit.
Four: the magnetic state of the magnetic circuit open circuit and closed circuit state will usually not soft when the single magnet called the open state; when the magnet in the magnetic flux loop by and soft iron together constitute when call this magnet in closed state. |
