when 2 different cpnducting materials r brought together and given a supply, there exist a potential difference between the 2.since these are 2 differt materials and an emf will be induced which is called thermo emf
Three primary electromagnetic field (EMF) hazards include thermal effects, which can cause tissue heating; non-thermal effects, which may impact biological processes and cell functions; and interference with medical devices, such as pacemakers. Prolonged exposure to high levels of EMF can lead to potential health risks, including increased cancer risk, although scientific consensus on these effects varies. It's essential to follow safety guidelines to minimize exposure and mitigate these hazards.
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 ?
thermal power is the heat used to produce electricity

Bcoz the emf which is to be measured is less than emf of driving cell....

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

Unbelievable - EMF song - was created in 1990.
