If we start discussing about the EMF or Electro-magnetic force in electronics or electrical technology. In simple words, EMF is the electrical action produced by a non-electrical source. Devices (known as transducers) provide an EMF by converting other forms of energy into electrical energy, Energy is converted from one form to another in the generator or battery as the device does work on the electric charge being transferred within itself. One terminal of the device becomes positively charged, the other becomes negatively charged. The work done on a unit of electric charge, or the energy thereby gained per unit electric charge, is the electromotive force.
The formula of EMF (Electro-Magnetic Force) is E=W/Q
Where,
- E = Electromotive force
- W = Work done
- Q = Charge
Line of Forces
Line of force, in physics, way followed by "an electric charge free to move in an electric field or a mass free to move in a gravitational field, or by and large any suitable test molecule in a given force field. All the more conceptually, lines of force are lines in any such force field the digression of which anytime provides the field guidance by then and the thickness of which gives the size of the field. The idea of lines of force was brought into material science during the 1830s by the English researcher Michael Faraday, who considered attractive and electric impacts in the locale around a magnet or electric charge as a property of the district as opposed with an impact occurring a ways off from a reason.
Simplest Definitions & Conclusions
Line of Forces mean "an imaginary line which represents the strength and direction of a magnetic".Electromotive force, is energy per unit electric charge that is imparted by an energy source.
