i know it has to do with electro magnets and motors and dynamos but i dunno wt it means... i thought it was electro motive force but apparently im wrong

 

It can also stand for "electromagnetic field".

No you are right EMF means electromotive force Its the same as voltage but emf is usually used for batteries and voltage is used to describe the voltage drop on resistors or whatever.

So is it wrong when people use it for electrmagnetic force? I constantly see people use it that way. Is it just a matter of opinion or something?

yay so it is good. tnks and you casn close this thread

No its not wrong as you know what are you doing

 

An interesting insight was provided in this thread: http://forum.allaboutcircuits.com/showthread.php?t=8592

My understanding is that EMF describes the electromotive-force and not the electromagnetic-field - we describe the latter almost ubiquitously as the EM-field.

actually im studying for my matsec examination to get the o.level degree. the exam is in 2 days

 

e.m.f. - electro-motive force is the quantity, while the volt is the unit of measure.
