what will happen if the insulating coat of some wires fell off and current can travel through the soft iron core? If the core is ungrounded then the core will just be energized to the voltage level of which ever winding (primary or secondary) became shorted to it (neglecting electrostatics etc.). If the core is grounded (likely) then current can flow and ...

First: the iron core of a transformer is not made of a solid iron , but is composed of thin sheets of iron, isolated against each other. Otherwise you would have circular currents in the core. But even so, if just e very short piece of your wire has no insulation, there would not be a current trough the core, since the second pole is mission, so just the ...

For a spin in an not excessively strong external magnetic field we can ignore the spatial part of the wave function and use an effective spin Hamiltonian. For a single electron spin this is the $$H=g\mu_B \vec B \cdot \vec S$$, where g=-2. The solutions are simply $|+\rangle$ and $|-\rangle$, with eigenvalues $\pm \frac{1}{2} g\mu_B$. Whether these wave ...

The principled way to answer this question is to write down the SchrÃ¶dinger equation for a particle in magnetic field and try to solve it. From the context of the question it seems that you are talking about an electron with spin-1/2 - the case that is treated extensively in textbooks, including its motion in magnetic field. However, it is not clear whether ...
