A toroidal core has a rectangular cross section as shown in Fig. P1.16a. It is wound with a coil having 100 turns. The B−H characteristic of the core may be represented by the linearized magnetization curve of Fig. P1.16b.
(a) Determine the inductance of the coil if the flux density in any part of the core is below 1:0 Wb = m2.
(b) Determine the maximum value of the current for the condition of part (a).
(c) Determine the minimum value of the current for which the complete core has a flux density of 1:0 Wb = m2Â or greater.
