EMF stands for "electromotive force" and is (more or less) a synonym for voltage. Despite the name, it's not really a "force" in the physical sense (EMF is measured in, unsurprisingly, volts, while forces are measured in newtons), and is more properly referred to as a potential.

What is emf in physics?
EMF, or electromotive force, is a measure of the energy provided by a source (such as a battery) to move a unit charge around a closed circuit. It is responsible for driving the flow of electric current in a circuit. EMF is measured in volts.
What is meant by electro-motive force?
Electro-motive force (EMF) is a measure of the electrical energy provided by a voltage source to drive current in a circuit. It is the force that pushes electrons through a circuit, creating a flow of electric charge. EMF is typically measured in volts.
How to measure the electromotive force (EMF) of a cell accurately?
To measure the electromotive force (EMF) of a cell accurately, use a voltmeter with high precision and connect it to the terminals of the cell. Ensure the cell is not connected to any external circuit during the measurement to prevent errors. Take multiple readings and calculate the average to minimize inaccuracies.
Does a moving airplane develop a large electromagnetic force (emf)?
No, a moving airplane does not develop a large electromagnetic force (emf).
What is the induced electromotive force (EMF) in this loop?
The induced electromotive force (EMF) in a loop is the voltage generated when there is a change in magnetic field within the loop.
Volts are a mesurement of what characteristic of electricity?
Volts are the measure of Eletro motive force. (EMF)

Does a moving airplane develop a large electromagnetic force (emf)?
No, a moving airplane does not develop a large electromagnetic force (emf).
How do you measure EMF?
Use a voltmeter.
What can emf of electromotive force also be called?
electro magnetic force
What is the induced electromotive force (EMF) in this loop?
The induced electromotive force (EMF) in a loop is the voltage generated when there is a change in magnetic field within the loop.
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 do you find voltage when amps is known?
You don't. If you know how many Amperes in an electrical circuit and also what the total resistance in the circuit is, then EMF (Volts) = current (Amps) x resistance (in Ohms). EMF stands for Electromotive Force, and its unit of measure is the Volt.
To measure EMF you would use a(n)?
"voltmeter"
