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.

EMF measures the electromotive force, which quantifies the electric potential difference between two points in a circuit. It is a measure of how much energy is drawn from a source (such as a battery) to move charge through the circuit.
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.
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.
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.
No, a moving airplane does not develop a large electromagnetic force (emf).
The induced electromotive force (EMF) in a loop is the voltage generated when there is a change in magnetic field within the loop.
