3.5. A laminated toroidal iron core has a mean magnetic path of diameter 15 cm and relative permeability 1000. The core has a circular cross-section of diameter 2 cm and a coil with 100 turns. The flux density in the core is 1T. Calculate
(a) the value of magnetic field strength H in the core
(b) the required coil MMF
(c) the coil current
(d) the coil flux
(e) the coil flux linkage
(f) the coil inductance from the coil flux-linkage
