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) t...
