emf in volts
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.
EMF is greater
How do you proof of the existence of back emf ?
The emf equation of signal phase transform
21
It is the souce that produce the emf force that drive the electron in a metal material
emf in volts
Bcoz the emf which is to be measured is less than emf of driving cell....

EMF - band - ended in 2009.
EMF - band - was created in 1989.

Scientists are still struggling on what are the sources of earth's magnetic field (EMF). The facts support the notion that the EMF has reversed its direction several times in earth's history. When the EMF reverses, the EMF intensity will be weakened. Some evidence supports that the EMF intensity is now peaking and is due for a complete reversal in thousands of years. So yes, the EMF will be weakening. What we should worry about is what effects do the sun's activities have upon the EMF in our lifetime. The solar winds can weaken the EMF too. Scientists are predicting major solar activities coming (check the related link). ======================
