Magnetic Field and Electric Field: Two Sides Of A same Coin

Probably, I won’t be able to give a satisfying answer to this question, but it’s the risk we take when we ask the Why of a physical phenomenon —instead of how physics can describe a natural phenomenon— and we don’t want a metaphysical answer. I don’t know how to give a direct answer, so I’m going to make a brief review of the milestones that have characterized this branch of physics (electromagnetism), with the hope  to remove some doubt.


Until the early decades of the 1800’s, experiments conducted to investigate electrical phenomena were completely separate from those focused on magnetic phenomena. Then, in 1820, Hans Christian Oersted —a Danish physicist and chemist— saw by chance that the needle of a compass is deflected from magnetic north if placed near a wire in which an electric current is flowing. Repeating the experience several times in a rigorous way, he demonstrated that an electric current generates a magnetic field, establishing for the first time a relationship between magnetism and electricity.


As soon as the French physicist and mathematician André-Marie Ampere learned of Oersted’s discovery, he began his experiments, in turn coming to some amazing conclusions. Not only he established in a formal way that a current-carrying circuit behaves like a magnet, but he also hypothesized that in a permanent magnet there are “electrodynamic molecules” responsible for the magnetic field at the macroscopic level. 
And that is exactly what happens.
Although the phenomenon is more complex, we can say that, in ferromagnetic materials, spin and motion of electrons generate small magnetic fields which, aligning along a privileged direction (magnetic polarization), add themselves vectorially, producing the macroscopic magnetic field.
The amazing thing is that Ampere’s intuition took place about 70 years before the discovery of electron by J. J. Thomson (1897).


Ampere, however, was not the only one interested in the interaction between current and magnetism. After his colleagues’ discoveries, Michael Faraday —an English chemist and physicist— wondered if it was possible to reverse the phenomenon, that is, if it were possible to generate electricity from a magnetic field. In 1831, after several experiments, he reached the conclusion that, in a circuit, an induced electromotive force is created each time the magnetic flux (number of lines) through the surface bounded by the circuit is changed. And it’s important to remember that Faraday’s law of induction is at the bottom of electric motors, alternators, electric generators and transformers’ working principles.

Thus, up to this point, the magicians of physics had determined that an electric field is linked to an electric charge and that a magnetic field is linked to a moving charge. 


Then, in 1864, the Scottish mathematician and physicist James Clerk Maxwell developed a theory that includes all the observations, the experiments and the laws known until the first half of the nineteenth century, regarding this branch of physics. In fact, with his system of equations, he proved that electricity and magnetism (and light) are manifestations of the same phenomenon: the electromagnetic field. With them, he also  introduced the concept of electromagnetic waves which, about 20 years after, were discovered experimentally by the German physicist Heinrich Rudolf Hertz, opening the door to modern technology (from radio to cellular phone and beyond).

With Maxwell’s equations (that predict the existence of waves having a speed equal to that of light) and all the charges’ “activity”, it was no longer possible to avoid the big question: 
With respect to which inertial frame of reference are they moving? 
A charge may be in motion  with respect to the observer, likewise, the latter can be in movement with respect to the charge. Now, can you guess who was the first theoretical physicist to give a formal statement of this ambiguity?
Right! In 1905, Albert Einstein published a paper entitled On the Electrodynamics of Moving Bodies exposing the theory known later as special relativity.


As already mentioned, a magnetic field and an electric field are two different manifestations of the electromagnetic field. But in other words, we can say that it’s the electromagnetic field to have physical relevance and, according to the inertial reference frame in which we observe a phenomenon, it may appear as an electric field, a magnetic field or a superposition of the two.

I realized why I like to watch the street lights turn colors in the middle of the night. It reminds me that the world will go on whether you are there or not. But simply being there is half the challenge. Simply being in the present. Not lost in past and future. Just being present can turn those lights. They can sense you. Cause change.

If you see her, tell her it doesn’t snow in Colorado.
Tell her all this stuff falling from the sky is just sawdust from the stilts I’ve been carving for my short temper. Tell her there’s a tambourine in my chest, and yes, she still shakes me. Too bad love is an Etch-a-Sketch, good thing love is an Etch-a-Sketch.
If you see her, tell her I’ve been running towards my life like Laura Ingalls running down that hill in her flowered dress, I wore a flowered dress to my birthday boy party.
Don’t look at me like that.
I’m not the box the gift came in.
This heart is my Sunday best, grass stained from the day I discovered her neck tasted like the reed of my first saxophone. If I could still play, I’d play the softest song, a moth in the lamplight, a snowglobe turning upside-down, Michelle Obama buttoning her husband’s bulletproof vest.
We are all fragile, and fraying
Praying we can hold the tire swing through summer.
My mood swings with its feet dangling in the river, so when my sadness reaches the ocean it turns to salt
If you see her, tell her the moon is all her fault.
Love; a trapdoor of light - even when it’s gone, it’s somewhere.
Tonight, I buried her time capsule in the ball field, for every time running for home meant running towards her - next time, I will know to listen when the umpire tells me I’m safe.
Next time, I will know it’s normal to have a hard time breathing when you shake the dust.
We make everything so complicated.
Sometimes, the message in the bottle is
‘Don’t drink so much - there’s too much Novocaine in our wisdom teeth already’.
Every window begs to be open when the storm comes. I dig seed holes in my pillow and dream of clock towers whistling at lightning, this upside-down umbrella is a teacup for God.
The puddles in my eyes are monuments of grief crumbling beneath moss.
You can spend your whole life wearing a life vest in the desert; it took me so long to burn those fire escapes, but I know neither of us are the felonies on our record players. I know the music we were trying to make.
Every one of us is a Mack truck with a soft bed inside.
I’ve got my thumb out on the highway, and I know she doesn’t drive this way.
If you see her, tell her I made a song from the dial tone. I made a papier-mâché glider plane from our unfinished poem.
Take the elevator to the parking garage rooftop, take a cigar box full of feather pens and write what you see.
The bassinet of my mouth unfurling its ribbons to raise my voice honest, honestly.
She was an anthem.
I was a stadium of patriots with their hands on their hearts.
Honestly, my hand is still on my heart as the fireworks announce the end of the game, and the colours in the sky chase the birds inside.
Have you seen the nest they are building from everything we left behind?
