Atoroid filled with a magnetic substance carries a steady current of 1.9 a. the coil contains 1200 turns, has an average radius of 3.86 cm. the magnetic field through the toroid is 0.289683 t. assume the flux density is constant. what is the magnetic field strength h within the core in the absence of the magnetic substance? answer in units of a/m. 013 (part 2 of 2)
determine the permeability of the core material. answer in units of wb/a m.
