Only the relative direction they are moving. EMF, measured in Volts, travels along a conductor, perhaps because a magnetic field has built up around the conductor.
When that magnetic field collapses, CEMF, or counter-EMF is generated in the conductor, and it travels in the opposite direction of the original EMF, countering the original flow of electricity.
EMF is Electromotive Force, and is one component of measuring electricity. EMF is measured in Volts, and represents the 'pressure' moving the electricity along.

What are the differences between potential difference and emf?
Potential difference is the difference in electric potential energy between two points in a circuit, while electromotive force (emf) is the total energy provided per unit charge by a battery or voltage source. In other words, potential difference measures the voltage drop across a component in a circuit, while emf represents the energy per unit charge supplied by the source.
What is the relationship between EMF and potential difference in an electrical circuit?
The relationship between EMF (electromotive force) and potential difference in an electrical circuit is that EMF is the total energy supplied by a source, while potential difference is the energy transferred per unit charge as it moves through the circuit. In simpler terms, EMF is the total push provided by the power source, while potential difference is the push experienced by the charges as they flow through the circuit.
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.
Can the potential difference across a battery be greater than its EMF?
Yes, the potential difference across a battery can be greater than its EMF when the battery is connected in a circuit and current is flowing through it. This can happen due to internal resistance within the battery that causes a voltage drop.
What is the phenomenon of emf development between two different metals placed in contact known as?
The phenomenon of EMF development between two different metals placed in contact is known as the Seebeck effect or thermoelectric effect. It occurs when there is a temperature difference between the two metals, leading to the generation of an electromotive force (EMF) or voltage. This effect forms the basis of thermocouples used in temperature measurement and sensing applications.

What is the difference between the emf of a battery and the lost volts when discharging called?
Internal resistance
What is the difference between Counter-electromotive force and back emf?
They are Same for dc motor

What is the difference between emf and mmf?
emf is electromotive force mmf is magnetic motive force emf drives electon where as mmf drives magnetic field
What is the term for he phenomenon of emf development between two different metals placed in contact?
The term for the phenomenon of emf development between two different metals placed in contact is called the thermoelectric effect. This effect occurs because of the temperature difference between the two metals, which creates a potential difference or voltage.
Difference between voltage and emf?
'Voltage' is simply another term for 'potential difference', and an electromotive force is the open-circuit, or no-load, potential difference of a source such as a battery or generator.
What is the potential difference between two points in a circuit is called?
Voltage drop
Another name for EMF?
"Potential difference" or "Voltage".
Why volt meter is always placed in parallel?
Because the quantity it measures is 'EMF' or 'potential difference', that is,the difference in potential between two points. There may be 1 or 1,000circuit components between the two points.
What is the difference between a DC motor and a generator in terms of EMF?
During the operation of a DC motor, EMF is created across its terminals using an external source. Whereas, in a DC generator EMF is created across its terminal based on principle of dynamically induced EMF. So talking in terms of EMF, in DC motor EMF is consumed by the motor coil and utilized to rotate the axle. On the other hand, in DC generator EMF developed across coil is transfered to a load or a battery and consumed by them.
