What is electromative force?
Electromotive force (EMF) is a term used to describe the voltage generated by a source of electrical energy, such as a battery or generator. It represents the driving force that pushes electric charges through a circuit. EMF is measured in volts and is often abbreviated as "E".
Can iron absorb EMF?
No, as a conductor an EMF would be distributed through-out the metal body.
In colomn answer of difference between statically indused emf and dynamicaly indused emf?
Statically induced emf is produced by the relative motion between a conductor and a magnetic field, while dynamically induced emf is generated due to a change in the magnetic field strength experienced by a conductor. Statically induced emf does not require any physical movement of the conductor, while dynamically induced emf is produced when the magnetic field changes over time.
How does lead block electromagnetic fields (EMF)?
Lead is a dense material that can effectively block electromagnetic fields (EMF) because it absorbs and deflects the energy from the EMF waves, preventing them from passing through.
Is emf a scalar or vector quantity?
Emf has direction within a current loop, though it is not scalar. It's a bit between though as direction should be otherwise accounted for when discussing induced Emf. Not quite either.
What do the letters emf stand for?
for "ElectroMotive Force" . . . what we casually call "voltage".
What emf stands for?
Electromagnetic field (induces around the metal when current flows through it). Another opinion: Nope ! 'EMF' stands for 'Electromotive Force' . We refer to it casually as 'voltage'.
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 voltage used to make current flow?
Yes. Another term for voltage is EMF, electro-motive-force.
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.
Why do you measure emf with a potentiometer not with voltmeter?
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
Is earths magnetic field slowly reducing?
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). ======================
While discharging which is greater TPD or EMF?
EMF is greater
When was EMF - band - created?
EMF - band - was created in 1989.
When did EMF - band - end?
EMF - band - ended in 2009.
How do you prove the existence of back EMF?
How do you proof of the existence of back emf ?
