assuming you mean electromotive force:
emf is the main principle behind power Transformers. emf also comes in the form of radio waves, which are used for radio transmission (obviously)

How are emf measured?
emf in volts
Does motional emf call induced emf?
yes indused emf is also called motional emf. If an open coil is subjected to a variable magnetic field, at the ends of the coil a potential difference is induced which is called induced emf. If a coil is connected to an emf source and switched on, the rising current will produced an variable magnetic field which in turn produces an emf. It is called back emf.
While discharging which is greater TPD or EMF?
EMF is greater
How do you prove the existence of back EMF?
How do you proof of the existence of back emf ?
What does the emf equation of asingle phase transformer do?
The emf equation of signal phase transform
What happens to emf as a battery is used?
The emf of a batter as it is used will stay the same.
What is emf in physics?
emf is the electromotive force and is used as another word for voltage generated by a battery or by the magnetic force according to Faraday's law
How are emf measured?
emf in volts
Why emf of battery driving potentiometer is greater than emf of the cell to be measured?
Bcoz the emf which is to be measured is less than emf of driving cell....

Is lenz law used to find induced EMF's?
It's primary usage is to determine the nature of an induced EMF from changes in the magnetic flux through a circuit. However, you must use Faraday's Law (and a unit conversion factor) to determine the SIZE of such an EMF.
When did EMF - band - end?
EMF - band - ended in 2009.
When was EMF - band - created?
EMF - band - was created in 1989.
