Does there exist a rigorous general mathematical proof for $M <\sqrt{L_1L_2}$?
Does there exist a rigorous general mathematical proof for $M <\sqrt{L_1L_2}$? Here $M$ is the mutual inductance between two conductors and $L_1$ and $L_2$ are their respective self-inductances. (...

Does the presence of a disconnected coil nearby affect the self-inductance of a coil under test?
Picture two coils in close proximity. They have the same dimensions and are located co-axially, with a small gap between then (like Helmholtz coils, but much closer together than in the standard ...

Finding the Magnetic Field within a solenoid
So, I have to find the magnetic field within a solenoid such that the field at a point(on axis) is half than that it would be at the centre. Length of the solenoid is 20cm and the current through it ...

Magnetic Field Lines in a Circular Solenoid
We know about magnetic field lines in a circular loop and a solenoid. While studying them, I thought about how the magnetic field lines would be in a solenoid made circular by bending, forming ...

Are Idealized Transformers Realizable?
Since parasitic capacitance in an inductor is always in parallel with its inductance, would this effectively become analogous to magnetic remanence exhibited within rebars (made from carbon steel) ...
