Steady state , Ohms law, Inductor circuit
$B_{\phi} = LI$
$\frac{\partial B_{\phi}}{\partial t} = L \frac{dI}{dt}$
$\epsilon = -L \frac{dI}{dt}$
Now, Let's say that my circuit has a battery, a wire and a certain inductance.
The battery has a ...

Product of Capacitance and inductance in parallel plates
I was solving this problem:
I was asked to find the capacitance per unit length, which I did (in cgs units)
$$C=\frac{w}{4\pi h}$$
and to find the inductance per unit length
$$L=\frac{4\pi h}{c^{2}...

An *actual*, relativistic, intuitive explanation for inductance…?
I searched high and low, and as far as I can tell, after years, there is not a single video or site that actually explains inductance in an intuitive way.
I mean an actual explanation. Not “Faraday’s ...
