Definition
Electromagnetic force ( left hand Fleming Rule )
Biggest electromagnetic force scale when direction of vertical magnetic field with current, and increases is proportional with conductor length, big of current, and magnetic field strength.
Teknologi dan Rekayasa
Left Hand Fleming Rule
Relation between direction of magnetic force lines, current and strength ( impulse ) always permanent like shown in to be upper. This connection called as left hand principle Fleming.
If left hand finger is bended [by] like drawing beside, hence the hand radius will show different direction.
Thumb : direction of ImpulseHand finger : direction of Electric currentForefinger : Magnetic force lines
Teknologi dan Rekayasa
Left Hand Fleming Rule
Like shown to drawing, when coil packed into a magnetic field, current flows with opposite orientation to left side and right, and magnetic force yielded based on left hand principle Fleming, so that coil creates impulse to turn around, because this revolution takes place continuous, hence required by commutator and brush.

Electric Generator Concept
Teknologi dan Rekayasa
Function of electromagnetic induction and
induction of electromotive
Showing above drawing a magnet is moved quickly in a coil.
If magnet moved like that in coil, strain will be yielded and lamp will blaze. On the
contrary if permanent magnet in place of hence lamp will die.
Teknologi dan Rekayasa
A phenomenon so-called right hand law happened between magnetic force lines directions, conductor residing in depth moved and direction of induction electromotive force ( direction of electric current ).
Like shown to drawing, if electrical hand finger is bended [by] hence forefinger will show direction of magnetic force lines, thumb shows direction of conductor impulse and hand finger shows direction of induction electromotive force.
Right Hand Rule
Teknologi dan Rekayasa
Level of electromotive force changes is proportional with elements following:
Magnetic force strength Conductor length ( magnetic induction increases if length to increase) Speed of rotary conductor
Electromotive force
Teknologi dan Rekayasa
Rectification of Electromotive force
To yield continuous electromotive force, conductor must continuously protected from magnetic flux.
This thing can be reached by the way of making rotary conductor in magnetic field or with magnet and conductor in a state of keeping quiet in place.
Teknologi dan Rekayasa
Rectification of Electromotive force
An alternating current generator usually applied to yield energy. When rotary coil at a speed of permanent in magnetic field, electromotive force at fickle coil.
Electromotive force yielded in this way is called as alternating current electromotive force. If this electricity applied as it is ( alternating current ) hence called as alternating current generator.
Teknologi dan Rekayasa
Generator
When rotary power wheel, magnetic flux in peripatetic stator with impulse repeatedly, so that strain AC induceed in lighting coil or charging coil.
Direct alternating current applied for equipments using source of electricity AC like headlight. While to filling battery, alternating current experiences concurrent by diode before doing impregnation.

How To Work
Pump shaft will rotate if the rotary actuator.
Because rotary pump shaft of impeller with rotary impeller blades
The fluid in it will rotate so that accentual and the speed rising and thrown from middle pumped to passage which is in the form of volut or spiral then out through nozzle
Teknologi dan Rekayasa
How To Work
Function of pump impeller is change mechanical energy that is revolution of impeller becomes fluid dissociation energy of diatomic ( fluid).

Compressor is Compress device or air compression equally compressor is compressed air producer.
Because compression process, air has higher level dividing valve
Compared to area air pressure (1 atm).
