It's a wonder ...

<RAMBLE>
It's a wonder that any of us get to grips with the understanding of electricity, when the fundamental lessons are impossible to
realise, starting with two point charges one metre apart in a vacuum.
Perhaps that is why the SI system defines the Ampere and not the Coulomb as its fundamental unit, but whoever has realised two infinitely long parallel wires one metre apart?
From the early days before the revelation of J.J.Thomson, it was thought that electricity was some form of fluid, and that gave rise to the weird name of Rheostat as " Stream Control" and also what we now just refer to as a bit of wire, the Rheofore.
What is truly amazing, though, is the theories developed by James Clerk Maxwell, considering that he did not have the benefit of vector calculus and had to deal with each dimension separately.

I see that a certain BS specialist has decided not to make a fool of himself with the curl operation again.
Wise move.
