Back EMF Tee
The counter-electromotive force (abbreviated counter emf, or CEMF ) 1 is the voltage, or electromotive force, that pushes against the current which induces it, is caused by a changing electromagnetic field. It's represented by Lenz's Law of electromagnetism. Back electromotive force is a voltage that occurs in electric motors where there is relative motion between the armature of the motor and the external magnetic field. Counter emf is a voltage developed in an inductor network by a pulsating current or an alternating current. 2 The voltage's polarity is at every moment the reverse of the input voltage 3 4 In a generator using a rotating armature and, in the presence of a magnetic flux, the conductors cut the magnetic field lines as they rotate. The changing field strength produces a voltage in the coil; the motor is acting like a generator.. (Faraday's law of induction.) This voltage opposes the original applied voltage; therefore, it is called "counter-electromotive force". (by Lenz's law.) With a lower overall voltage across the armature, the current flowing into the motor coils is reduced. 5

Good stuff! Although, I do have a sneaking suspicion that this is cursed. You see, whenever i dawn this top-teir, soft, stylish shirt - I proceed to pass out within 46 seconds. The mere act of making contact with the material insues the process of this countdown starting. If I do not quit contact, i will lose conciousness the exact moment the countown hits 0. And when I regain clarity, I find myself in a bathtub - never mine, but a bathtub nevertheless. In the bathtub, there is always various colours of hairdye. I then have to go back home, shirt stained with dye. Very fashionable though! 10/10
Smooth transaction and nice product, shipping was quick!
good very good worth money!
5 out of 5 I love when people start reading the definition. It's halourious
10/10 yes much good 10/10 would buy again
Fit is true to size, good quality material. Graphics applied well (not off-center or angled as with some products). Quick shipment.
gooderesting the gooderesting thing ever made
Got it for a friend! He loved it
Size was accurate, and printed text was as displayed online. Doesn't hurt that the material is pretty soft either.
mine says "ass" on it lol
Good Decent, comfortable by all means
My wife bought this for me, my only thing about the shirt, is the big Vernon on the front. I think I would prefer it situated and smaller type as if overva pocket. Other than that I love it. Seems to be of good quality and easy wearability, but I have only tried it on, so am uncertain. Thank you for making my day
shirt made me cum
Dick Aww man I love this shirt for eating
people shat on my shirt that said shart and im mad they took a shit on it instead of a shart
Necero's shirt i can use this in almost every phrase. This shirt allows me to do some great stuff with my kids and grandkids! i'd love for anyone who says same to get this shirt!

Amazing This shirt is SOOOOO comfortable and I love the definition
