force

 [fors]
energy or power; that which originates or arrests motion or other activity.
Forces resulting from a fall are transmitted up to the spine through the long leg bones and pelvis. From McQuillan et al., 2002.
electromotive force the force that, by reason of differences in potential, causes a flow of electricity from one place to another, giving rise to an electric current.
reserve force energy above that required for normal functioning. In the heart it is the power that will take care of the additional circulatory burden imposed by bodily exertion.
shearing f's see shear.
van der Waals f's the relatively weak, short-range forces of attraction existing between atoms and molecules, which results in the attraction of nonpolar organic compounds to each other (hydrophobic bonding).

e·lec·tro·mo·tive force (EMF),

the force (measured in volts) that causes the flow of electricity from one point to another.

electromotive force (EMF)

[-mō′tiv]
the electric potential, or ability of electric energy to perform work. EMF is usually measured in joules per coulomb, or volts. The higher the voltage, the greater the potential of electric energy. Any device, such as a storage battery, that converts some form of energy into electricity is a source of EMF.

n the ability of electrical energy to perform work, measured in volts or joules per coulomb.

In case of AC furnaces, the mixing process cannot be controlled and the forces that are created by joining the eddy current magnetic fields, 50 Hz time varying magnetic field and induced electromotive forces, are not in accordance with the weight of the molten metal that has to be mixed.
In order to describe the resting and action potential in giant squid axons, Hodgkin (1964) partitioned the series conductance and electromotive force of the equivalent circuit into a number of conductances (one for [Na.

In this paper the performance characteristics of different types of the PMBLDC motor drives with identical fundamental harmonic components of their back electromotive forces are investigated and compared as well as the performance of a sinusoidal-type PMBLDC motor supplied by two- and five-level inverters are investigated and compared to each other.
Therefore, these currents will generate an electromotive force which is only across the lower receiver coil.
