Ferromagnetic materials, magnetic circuit diagram method

Is the composition of the magnetic circuit of ferromagnetic material (,. Which can calculate the flux values: m: BA: 1.28x9, 6x10 for a 'a 1.22 × 10-2Wb proved that the obtained flux m value obtained with the heuristic value of the same. When H and B, respectively,[link widoczny dla zalogowanych], the maximum value for the coordinates of / /, the corresponding magnetic induction B6, the corresponding coil current, as 9LH,. 5) If the coil current,> ;. To be in Figure 3 the three magnetization curves 1 ', 2', 3 'mapping by the solution, and must (10) is calculated accordingly. B = mouth Ⅳ, an IO [JLH (9), respectively, / / value of 200 and 400 into (9) to calculate the corresponding value of 1.557, and I. B 1, according to B and / / the value in Figure 3, draw a straight line can be M. N. It and 2. The intersection of H and B values (210,1.557), is the composition of the magnetic circuit of ferromagnetic material (H, B), which calculated the flux values: m: B, 4:1.557 × 9.6 × 10 a: I. 476x10-26 experienced operators,[link widoczny dla zalogowanych], with the graphical method and the calculation results the same. Constant flux for the non-uniform magnetic negative branch of the computational method can be summarized as follows: a first horizontal axis magnetization curve of the magnetic field strength according to the maximum nominal value of Hb and the corresponding magnetic field 06 to calculate one of them; 2 if, \;,, find the equation B = mouth Ⅳ,[link widoczny dla zalogowanych], an engineering point of intersection with the magnetization curve (Ⅳ,, B), magnetic flux mBlA,[link widoczny dla zalogowanych], HH-, BBl ・ 3 If,>,, of equation B Ⅳ, an IO ~ magnetization curve and the intersection of HL (, B), magnetic flux m = B,[link widoczny dla zalogowanych],, H = 10H,, B = B.
