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.

How do you proof of the existence of back emf ?

Potential electromagnetic field (EMF) hazards are typically categorized into three overlapping areas: electric fields, magnetic fields, and radiofrequency fields. Electric fields arise from voltage sources, magnetic fields are generated by current flow, and radiofrequency fields are associated with wireless communications and broadcasting. Each of these areas can contribute to exposure risks depending on the intensity and duration of exposure. Understanding these categories helps in assessing and mitigating potential health impacts from EMF sources.

EMF - Unbelievable
Three things required to produce electromotive force (EMF) in an alternator are a magnetic field, a conductor, and relative motion between the magnetic field and the conductor.

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.
The three modes of a hazard are dormant, armed, and active.
