Consider the situation when almost all of the magnetic moments of a sample of a particular ferromagnetic metal are aligned. in this case, the magnetic field can be calculated as the permeability constant μ0 multiplied by the magnetic moment per unit volume. in a sample of iron, for example, where the number density of atoms is approximately 8.50 ✕ 1028 atoms/m3, the magnetic field can reach 1.99 t. if each electron contributes a magnetic moment of 9.27 ✕ 10−24 a · m2 (1 bohr magneton), how many electrons per atom contribute to the saturated field of iron?

In the circuit, the switch s has been open for a long time and r = 125 kohm. it is then suddenly closed. (a) determine the time constant before the switch is closed. s (b) determine the time constant after the switch is closed. _ s (c) let the switch be closed at t = 0. find the current in the switch as a function of time. (use t for time. express your answer in milliamps and seconds.) i(t) =_
