EMF meters can be purchased online at dedicated sites such as 'LessEMF', 'Home Depot' and 'EMF Center'. Alternatively, you could try your luck with finding one on eBay or Amazon.
Bcoz the emf which is to be measured is less than emf of driving cell....
yes..only the application is different.
In dc motor, the armature conductors are revolving in the magnetic field and emf is induced in the armature conductors. The direction of the induced emf is in opposite direction to the applied voltage as per Flemings left hand rule. So, the induced emf in motor is called as back emf or counter emf. Vydehi
emf is electromotive force mmf is magnetic motive force emf drives electon where as mmf drives magnetic field

EMF detectors can be purchased at stores such as Amazon and Home Depot. It is also possible to download an EMF detector app to your phone, computer, or tablet.
EMF (E''electromotive Force'') is another term for Volts, hence the E in electronic formulas and EMF is measured with a volt meter. A potentiometer is not a meter at all, it is a variable resistor

The EMF works by detecting electromagnetic fields that are present. You use an EMF detector, like a K-II meter to detect these fields. EMF fields that are too high can be dangerous, and can cause nausea, dizziness, paranoia, and other things.
An EMF (electromagnetic field) meter is believed to detect changes in electromagnetic energy, which some believe is associated with spirits or ghosts. Ghost hunters use EMF meters to identify fluctuations in electromagnetic fields, which they believe may indicate a ghostly presence in a location. However, it is important to note that there is no scientific evidence to support the use of EMF meters for detecting ghosts.
A meter is a measure of length slightly longer than three feet. You cannot buy a meter of milk.

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