An acronym for Electro-Motive Force, which is really a misconception in the world of physics, carried over many decades due to "convention". EMF was originally thought to be responsible for moving positive charge carriers through a medium, and of course, this was later found to be incorrect. Along with the fact that electrons are in fact negative charge carriers.
The EMF in a electrical circuit loop equals the product of the resistances and the respective currents through the resistances.

Electro Magnetic Fields- the numbers that show if there is paranormal activity. For example, if the number indicates that an EMF reading is high (i.e, 8.9), it means there is a certain sure of paranormal activity
TAPS members Steve & Brian on the Sci-Fi channel most of the time get high EMF readings

One Hit Wonder who's song "Unbelieveable" was stuck in everyone's head all through the '90s. EMF stands for "Epsom Mad Funkers" according to the band, but outraged elderly women swear it stands for "-Something- Mother Fuckers."
Person 1: "Yo, I totally have EMF stuck in my head! 'You're Unbelieveable...oohh!!'" *begins to drill through skull.*

The legendary resident of East PennsylMerica who is singlehandedly responsible for the vast majority of screams, grunts, airhorn blasts, jeep maulings, car crashes involving telephone poles, driveby Tonk-Tonk yellings, impressions of that fucking bear from Harvey Birdman and high-power muzzle flashes that occur in the Lehigh Valley. He is also an excellent and severely brutal mechanic, though sometimes known to intentionally self-immolate for his own amusement while on the clock at Junk-n-Shit Slowlube. Known to hang out with The Devil alot, over down there by the NW Field. E.M.F. is not to be trifled with, especially by those ascot-sporting foofter Hogwarts kids he verbally assaulted at Macs awhile back. Further proof that in addition to being a Kraut and hating republicans because they steal from us, he is also Really Fucking Loud.
E.M.F. once famously invented the word Dingleslaps on the same day his mother coined the term Muffinchops. Brutal.
